When we got an AeroPress in July 2018, we realized we needed a convenient way to heat the water to a specific temperature, since you should not be using boiling water for your AeroPress. I reviewed a number of adjustable temp kettles before deciding on this one. Specifically, I was looking for one with an easy to set temp that also remembered the previous setpoint. This one fit the bill, and we bought it a week after we bought the AeroPress.For over a year and a half, this has been cranking out hot water for us. Typically it is used twice each morning for coffee for my wife and I, who usually get up and moving at different times, and in the winter I use it considerably for making tea throughout the day.Turns out, maintaining the previous setpoint wasn't all that useful after all (though it still is nice), since my wife and I have settled on different temps for making coffee in the Aeropress. What is useful is the quick temps. With one button, it cycles through preset temps of 140, 176, 185, 190, 205, and 208 °F (or equivalent °C if in °C mode), and we've ended up using this almost exclusively. I brew coffee with the 176 °F setting, my wife uses 185 °F. Since you have to add water after you use the AeroPress (or milk/etc), I usually brew the coffee, then set the pot back on the base and tap the preset temp button several times to the 208 °F to top off my mug with really hot water, as I like hot drinks. So we typically are pressing this button numerous times per day, and they've obviously used quality buttons since it shows no signs of wearing out. The temp can be adjusted in 1 °F increments from the preset using the + and - buttons (and again, it always turns back on to the last used temp, whether that is a pre-set or custom temp). Adjustable range is 140 °F to 212 °F.Temp accuracy: If I put my meat thermometer right at the temp sensor, the thermometer reads ~2 °F higher than the kettle. Not a big deal, and explains why a roiling boil happens at a displayed 210 °F and it never reaches 212 °F.Hold button: By default, the pot shuts off when it reaches the set temp. Pressing "hold" will have the pot maintain the set temp for an hour before turning off. You can press hold as soon as you turn the pot on and it will climb to your set temp and hold. Great for turning the pot on and taking a shower, and it will be at just the right temp when you get back to it.Cleaning: They say to use only a "special" cleaner that they sell...go figure. Nah, I put half a pot of vinegar, half a pot of water, turn to the 208 °F preset and "hold" for an hour. When I get back to it all the calcium buildup is gone. Rinse with water and refill for your next use.Rust: I've seen people mention rust. One time I thought I saw signs of rust, but cleaning with vinegar removed it and I haven't seen it since. Maybe it was iron in the water or maybe something was growing. Not sure.Calcium: As with all pots used to boil hard water, calcium will build up on the bottom. This starts flaking off after some time, and with the spout going to the bottom of the pot any calcium flakes that break off will come right out of the spout immediately on pouring. This could be an issue depending on your point of view. If you don't like this, get a pot with a top-pour spout and this won't happen. Cleaning more often or using distilled water are two ways you can fix this. The other way is to just not drink your coffee/tea to the very bottom of your cup, i.e. don't tilt your cup "up" past horizontal and leave just a tad in the bottom and you won't accidentally "drink" these calcium bits.Other: The pot can swivel 360° on the base, and since it has a temp sensor in the pot the power and temp signals are transmitted through the use of a pin and 4 concentric rings of metal on bottom the pot that contact 5 spring loaded pins in the base (the power pins are recesses and cannot be touched on accident, plus the base will not supply power if the pot is missing). I have noticed (only occasionally) that something, I assume minor corrosion, will occasionally throw off the temp reading or recognizing that a pot is attached. Usually this seems to happen if you put the pot at a different angle then normal. If this happens, the fix is easy. With the pot fully lowered on the base, just swing it back and forth a few times until the temp display stops changing when the pot is rotated. Again, I've only noticed this once or twice. Could have just been a piece of dust or something got on a contact.Summary: Great pot, accurate temps, handy pre-sets, holds last temp in memory, reliable and long lasting. Will definitely order again if we need a replacement or if we want a dedicated one for our RV rather than taking this one with us.I repurchased this kettle after the previous version broke when the gooseneck spout separated from the joint at the connection point, probably because we never demineralized the kettle. The previous kettle was larger at 1.5L but this smaller one does the trick too.I like that the temperature control is precise and that there are several temperatures saved in the base's memory. While the user can't adjust these memory temperatures, at least it gets you close enough to fine tune the temp with the +/- buttons. We make various brews of coffee, green tea, black tea and herbal tea in our house and it's really nice to easily set different temperatures for each beverage.I once measured the temperature inside the kettle with a digital cooking thermometer and the read out was the same number as on the kettle, so I'm satisfied that the temperature is accurate.I haven't had any issues with the base going kaput, like others have. I suspect this may be in part because we've always used the protective cover that came with the base. In fact, the base from the kettle that broke still works great and we've kept it as a spare part to use with this new kettle if needed. I encourage others to always use the protective cover, too.2018 EDIT:Still five stars five years later, and I’m about to buy my third 1L bonavita kettle.I spent the week reading reviews figured I would try something different, but Amazon says I bought this pot five years ago, and it still working like new (and I use it every day).I don’t want to risk buying another brand where I cannot control the temperature the way I want. This kettle remembers your last setting when you push one button.You can set the temperature to anything you want it remembers it. There is a button that cycles through preset temperatures, but then the arrow keys allow you to zoom in on exactly the temperature you want. This is probably not very important for coffee or basic black tea, but if you are really a tea drinker temperatures vary dramatically (people brew Japanese green tea for example Starting at around 120°F). Although my favorite senchas brew from 160 to 170 F.When you push the button to heat the water, it remembers the last setting and it heats up to that setting and holds it the temperature to within about 1°. I believe there is a timeout feature but it has never intruded on my tea drinking. For your second and third brews you have to remember to hit one button when you put the pot back on the base (so it will hold the temperature).The gooseneck spout is the best there is for pouring into those little teapots, or for pour over coffee as well. But if you are very impatient this might be a disadvantage if filling a large cup is your only use for this pot.After reading complaints on Amazon of the temperature being off, I checked mine with a cooking thermometer at 170°F, it was spot on. This is the one that has been abuse for five years.My previous review below sucks (reading it five years later). I believe I was comparing the Bonavita kettle to the basic on off kettles. Shortly after I started using it there is no confusion whatsoever with what button to push. I mean come on there are only four buttons.For one person definitely choose the 1 L size. I keep mine full of water, or else if you don’t use it every day the water could become musty. The larger size for one person risks boiling the oxygen out of the water (which is not optimal for making tea or coffee). With the smaller size more freshwater is cycled through that hasn’t been boiled to death.~2013 EDIT:Its really hard to find a water pot that pours well (although most of the electric stainless steel ones do).. Havent actually used this yet for pour over, but I can tell it will work great (because you can aim the pour and the water volume seems about right)..CON;Slightly slower to heat water because it cycles on and off while the electronics control heating (no big deal for me). Pours slow if you just want to fill up a cup then dunk a tea bag in (kind of a pain).. If I did not want this for pour over use specifically, I would not recommend the skinny spout..PRO:Spout pours great for aiming into little teapots, or for pour over coffee.. The temp setting IMHO is great. Much more convenient than speed of heating. I have a manual induction water pot that heats very quickly. But it will boil like mad if I don't stay and watch it. This pot will hold a temp, so it is more convenient to walk away and come back in a few.I Haven't played with the temp enough to check it out completely. But it is at least adequate. It does not go full steam ahead to get up to the temp setting, so it takes a little longer (you can hear it cycling on/off). I believe it is slightly more quiet than my old electric pot. It does remember my last setting (now if only I could remember which button to push to start it.. I wish the main button were different than the others). I suppose I will eventually remember which one it is..I chose the smaller one because I only put the water I want to heat, into the pot (then expect an empty pot to dry afterwards). BUT I find it difficult to drain the pot completely .. When I try I end up pouring out the lid too.. Not a deal breaker. But I don't like my water to get stale. But leaving water in the pot can draw a musty smell over time, and heating the same water over multiple times will boil the oxygen out so it deosnt brew well (but perhaps Im overthinking this part)..Excellent temperature control and easy pour!!! Loved this one so much I gave one as a gift!One year into trading my coffee addiction to one for tea, it was time to invest in the proper tools of the trade. After falling into my usual Google rabbit hole, I landed on the Bonavita.1. Heating time: not as speedy as others, but that’s only a concern whilst you’re obsessively angst-ing over reviews - it’s plenty fast IRL.2. The UI is a tad clunky, but if you’re using the same settings daily, it’s fine.3. People made issue with having to press the ‘hold’ button to maintain temp whenever the kettle’s removed from the base. Whatever - hardly a herculean task.4. Haven’t experienced the ‘HI ERR’ glitch (yet).Otherwise, the Bonavita met my purchasing criteria: accurate temp control, BPA-free, small footprint, and a capacity that’s less than what’s required for an Italian wedding.I would highly recommend this unit as it’s increased my QOL by at least 2.75%. And, while it lacks some of the glossier features of newer products, I’m pretty sure people have managed to enjoy tea throughout antiquity without using an app.I was very excited to have received this shipping today because this item has great review.I must say I am very disappointed when I opened it. No only the kettle was very light weighted to a point that I am concern about durability. Most importantly I found a manufacturer defect. The opening of the gooseneck as shown on the picture has a irregular discolouration which almost looks like rust/raw metal.I've never return anything on Amazon and this will be my first item.I didn't expect the kind of quality with this price tag. Also the seller doesn't seems to be enthusiastic about learning customer feedback. The product isn't open for seller feedback on the most recent order.I absolutely loved this kettle and heard good things, but it's only been 2 months since I purchased it that it has already developed a light rust ring on the lid portion. I'm not happy to see this, and I'm even more worried to see what will come in the future for this kettle. I wish I read more into the reviews here on Amazon because it seems that it is a common issue, and even worse off that the company is horrible with service. Stay away from this product and company at all costs.After researching variable temperature kettles, I selected this Bonavita model based on the high rating. However, my experience was very disappointing. The digital temperature control was very inconsistent. It worked sometimes and other times would not work. This began several months after purchase. At this price point, I expect a manufacturer to stand behind their product. When I contacted the manufacturer, they would not warranty the product as more than a year had elapsed from the date of purchase until the date I reported it. It had failed prior to the expiry of the warranty, but Bonavita would not honor it. I don't mind paying a high price for a product, but I would hope to get a quality product and a manufacturer to stand behind it. Looking into the reviews a bit deeper, there are several other 1 star reviews, which to me would indicate a high product failure rate. Maybe you will get lucky, maybe not. This is my first Bonavita product and last. Back to the $4 Walmart kettle, which has performed better.The temperature control/display is particularly useful for brewing a green tea as the wrong temperature would ruin the flavor, the scent and the color. The goose neck is great for brewing drip coffee. It doesn't not boil water as quickly as many of the basic inexpensive kettles in the market. The temperature display usually does not get beyond 99 (instead of 100). I've only had this for 6-7 months but the temperature sensor is beginning to go (sometimes flickering between 70+ to 90+ when the rolling steam indicates the water has reached a full boil). At this price, I expected it to last at least 1 year or 2.
