So this is the first time I have purchased a kettle, and I love it. I love that it can handle both bagged tea and loose leaf tea in the infuser. The little handle to get the infuser out of it doesn't really get too hot after you brew your tea so it's easy to remove the tea so you don't over-brew it resulting in your beverage being too strong. At first I thought the KEEP WARM function didn't work, but after tinkering around with it for a while I figured out how to make it work. You can either select the keep warm function, then the temp. you want it to keep warm at, then hit the START BUTTON for it to work. Or you can hit the temp. you want, then the keep warm button, then the start button and it will work either way for 30 minutes. The temp. button you chose will flash and the water will start to heat up until it reaches the desired temp. After it reaches that temp, it will stop flashing and it will be solid, periodically within the 30 minutes it will start to heat up again and then it will stop when it's ready. it does this a few times within the 30 minutes that it is designed to stay warm for. Not very clear in the instructions that you have to hit the start button after selecting the temp and hitting the keep warm button, but after you figure it out it works great. FANTASTIC PRODUCT 10/10 I WOULD RECOMMEND.
