I absolutely love that this does not turn off unless I turn it off. I bought this because I have bottle baby kittens who are still needing formula. For a while, I used my crockpot to keep warm water in, but that got way too hot and make it difficult to maintain a warm (instead of scolding hot) temp for the formula. This bottle warmer has so many settings, and allows for the formula to stay perfect temp, or heat up super quick when I need it to. It's also not very large in size, so I can carry it with me pretty comfortably which is a huge plus since my kittens are eating every couple of hours. Also, when heating up, it doesn't make too loud of a noise like other bottle warmers. So I'm thankful for that too. Overall, this bottle warmer rocks!!
