I am no stranger to Hario products, I have found that almost all of them may be somewhat simplistic, but they are extremely functional. Ive been using this for the last month and I have been loving it.Some helpful information:I bought the 1.2L model and it is made in Japan, its stamped right there on the bottom of the kettle.The steel seems to be high quality, absolutely no rusting, even if it has had water in it 80-90% of the time.The kettle is induction compatible, works great on my induction stove.It lists 1.2L as the capacity, do remember that boiling water is quite violent, so really, you can safely boil about 800ml or so, maybe up to about 1l. You can easily store and serve up to about 1.2l in it.I have exclusively used bottled water in the kettle, as the local water here is ultra hard and is not great for making coffee or tea, and I am unable to install a proper filtration system that is able to reduce the hardness.I havent had to deep clean the thing since ive been using relatively clean water in it, but I imagine that its not very hard, just bring it to a boil with some citric acid if you have scale issues.As to using the kettle, it pours beautifully, a nice even stream that doesnt dribble. The handle stays nice and cool, and is comfortable to use. It works great for my coffee-making, be it with my french press, V60, or my Aeropress. I can imagine that its great for making tea as well.As a bit of helpful advice, if you need to boil about 500g/ml of water, fill it up to a little under the 2nd ridge on the inside, it should be just a little over 500g, giving you some buffer in case if you leave it on boil for a little too long, or if you just want to pour a bit extra.The only minor gripe I have with it, is that its a little hard to tell when the water is at a rolling boil at times unless you are right next to the kettle. Nothing whistles, there are no thermometers, and its not automatic, so you have to listen for the rumbling of the water within and watch for the steam that comes out from the vent in the lid.
