TLDR: We tried out three different bottle warmers. This one (Mom Cozy), the Philips Avent, and the Baby Brezza (non-smart one). We ended up going with the Baby Brezza because it had buttons that were easy to push and was the most consistent in getting room and fridge temp bottles to the optimal drinking temperature.The big issue with the Mom Cozy bottle warmer is that the buttons were so hard to push and even when using both hands and pressing hard, sometimes they still didn’t work. Not something I would be able to do with a screaming baby in one hand. Working buttons should be the bare minimum for a product. On top of that, this warmer heats via steam rather than water bath so the top of the bottle is very hot when you pull it out. Also, allegedly steam heating isn’t great for breast milk anyway and should really only be used for formula. Not an expert on that subject though.The Philips Avent was very simple which I loved, but was pretty inconsistent in getting the right temperature. Sometimes it was too hot or too cold, even with the same amount of liquid in the bottle. Both room temp and fridge temp bottles had the same issue with drinking temperature consistency. Another big drawback was that this warmer didn’t have a sound or ding to let you know it was done. You just have to watch it and if you leave it in for too long afterwards, the water bath continues to heat it up and it gets too hot. We ended up doing this several times because we forget it was in there.Finally, the Baby Brezza. We didn’t see any reason to spend extra money for the smart version of this product and still don’t feel we should have. This product has the option to do water bath OR steam heating. Neither of the previous two did both. The buttons were easy to push and although this one was less intuitive to use, it’s not that difficult once you know the two button process. Of the three we tested, this warmer most consistently got the bottle to a good drinking temperature. This warmer also has a timer with minutes and seconds countdown and it has a sound after it is done heating. The only drawback is that when you pour the water out, if you tilt it forward and then pour, some water gets trapped in the lip and then leaks down the front. If you just tilt it to the side and back and then pour, that seems to fix the issue. Overall, the best one of the three though.
