First of all, I was impressed with the product packaging, It came with instructions that were clear and written in good English. The instructions also included information on how to properly brew pour over coffee. So, I was able to understand how the product is supposed to work, even though it is pretty straight forward. I have owned the kettle for a week and I really appreciate that I can set the temperature to whatever temp I want (within the designated range) versus just having the options of preset temps. I found that the temperature of water, when heated in the kettle, is about 3-4 degrees Fahrenheit too low. In other words, if the desired temperature of the water is set to 200 deg F, when the kettle reaches that temp, it will actually be only about 196-197 degrees F - I verified this with two separate food thermometers. However, I just account for that when setting the desired temp - so I increase the temp accordingly. The inside of the kettle is actually all stainless, including the inside of the lid, which is great. The water heats to a boil in a reasonable amount of time. I really like this kettle and hope it lasts.
