Sometimes the bottles are really warm and sometimes they are still I've cold even though the machine says it 98.6 degrees. You can only use certain bottles with it and sometimes it leaks. I agree with other reviews it hard to do 1 handed while holding a screaming baby.

Got this for my baby shower as a gift, after two weeks of use it started to leak all over. Up to an ounce would leak out at a time and if you’re breastfeeding you know that milk is pure gold, you don’t want to lose ANY! Called the company directly and they said it was the adapter piece but in my opinion and my husbands it’s not the adapter piece, that piece fits fine on the bottle and doesn’t seem to have any defects. It’s the auction between the adapter and the rubber ring that gets pressed together when you are warming. The suction is poor, the way it was made it just not high quality for the price. This brand has other warmers I’d get before this one. I’ll be going with the Dr. Browns one now. Don’t waste your $50 on it! The only thing I’d say is a pro about this bottle warmer is that it is small and easy to travel with, for that I’d give it two stars.

Product work great for the first couple weeks, then it starts to leak when you flip it over. Cleaning it is a hassle, and now my milk isn’t even warm anymore. It’s still cold from being in the fridge but says that’s it’s 98.6 degrees warm.

I wanted to love this warmer, but it leaks almost every time. I make sure to get it all screwed on tightly each time, practiced with just water in the bottle, but it still leaks making a mess and wasting milk. Kind of a pain to clean after every use, but I would still prefer vs a water warmer if it didn't leak. I wish I could return, but am now past the return window. Will probably just use for a backup or travel.

It works but it leaks everytime and I hate wasting breast milk and it also makes a huge mess!

I haven’t even got to try it , isn’t compatible with all bottles ( Avent) to be exact , reading a lot about spillage another bad sign. Also cord is very bulky which is super annoying.

This bottle warmer is not convenient at all. You have to turn the bottle upside down so water is constantly leaking out. It looks nice and is a space saver but it’s takes too much effort with a crying baby.

Great concept, but the o-rings do not fit snug enough and it constantly leaks. I lose about 1/2 an oz to an oz every time I need to use an adapter. It also over heats the milk (tested with multiple thermometers). I love that it’s small and heats up quickly, but it’s a pain in the butt and I’ve been wasting formula and breast milk because of the design of the o-rings.

It warms the milk up just fine but the process of connecting it to the bottle and flipping upside down gets frustrating.. especially during middle of the night feedings. It seems to leak quite often and it does not connect to Mam bottles.

received this as a baby shower gift. it would've been better if it was battery operated for on the go. you have to be connected to an outlet. if the bottle is not on right, milk will leak. used this with avent glass bottles. also you constantly have to clean it because mold will build up from formula/breast milk touching the metal plate. also it starts to act up because I've used this in the middle of the night, as I change my baby I have the bottle warming up & sometimes it either never warms up & will display an error message or it'll say it's at 98.6 and the milk is still fridge cold. it also takes a long time to heat up especially when you have a fussy baby who's hungry.
