Quite decentArvosana 4/5
Quite pleased. The build quality feels very solid. The plastic handle feels like it might be the Achilles heel in the long run but will see. Buttons are so and so, but then would you really expect mechanical switches or such on a kettle.
Performance wise the kettle seems to undershoot the target temperature by around 3°C. Not a huge deal in my opinion, but depends on how accurate you want to be. The step is 5° so if you want to brew maccha at 80° you are stuck with 77° or 82° (or waiting for the overshoot to cool) Haven't tried the keep warm function to see how evenly it works (or if it ramps the temperature up and down)
Pouring wise the nozzle isn't the greatest and especially when you start approaching horizontal plane the lid can leak. It does beep all the time which really is more annoying than I anticipated. Not something I can't live with but... Jeesus..
Hard to say overall I'm pretty happy and I couldn't find anything better but.. It IS a shame it has some minor BUT ANNOYING design flaws.
