Works great!
This bottle warmer is excellent! I’ve tried a few and none of them seem to heat the milk at all. I tested this one using a wide mouth bottle filled with 2oz of water. I followed the directions for using a plastic bottle and selected the correct options and added the water. I then turned it on and watched it go. It isn’t loud while operating, but the nightlight is very small and hard to see. Not a big deal to me because I have small lights in my kitchen that I can turn on at night if I need to use this in the middle of the night. The settings on the machine are a little different than when you select options on the machine. It says for a plastic bottle with 2oz on quick is 2:30, but the time was automatic 3:30. I think you have to manually adjust the time according to what the manual suggests. It’s very neat that it spins around gently to ensure the bottle heats evenly. When I took the bottle out it wasn’t so hot that I couldn’t grab it, but I could tell it warmed it well. I obviously had the time too long because I didn’t realize until after that I needed to manually adjust it, but this was just a test run. The water was nice and hot, so I think it would have been perfectly warmed if I had only done 2:30 as recommended. My only issue is typically bottle warmers can also warm baby food, but there is no instruction or anything on how to heat it or how long. I might play around with it and give it a try when I’m ready to make baby food, but for now it’s excellent at heating bottles!

works well
Bc Babycare Bottle Warmer arrived quickly and is as described. It takes very little space on the counter, looks sleek and delivers! It only takes a few minutes to warm up a bottle and it works with both skinny (Dr.Brown's) and wide-mouth (Avent) bottles. It's intuitive and easy to use, and it can be used to defrost, warm up and keep the milk warm. Works well for us.

Rotating bottle warmer
Barely warms up faster then other baby bottle warmer. The timing for the 9 oz Philips Avent natural baby bottle with 160 mL only got milk to 92 F so if wanting to get to higher temp you have to let it heat for a little longer. Without a lid the water does evaporate pretty quickly requiring frequent refills. The design also makes it hard to wash. Build quality is excellent but with the larger footprint it takes up more counter space than other bottle warmers.
