I wish I would’ve read the review before purchasing this. It leaks when you need to turn it over and remove the bottle.

It worked fine for the first week but now it pours milk out every time we heat it. It does heat evenly but the seal sucks because the bottle has to be upside down. Wouldn't recommend this product for that reason alone. And yes, we're using the O rings and the correct adapter.

It leaks no matter what we do and we waste so much breast milk trying to heat it up

This worked perfectly for us for maybe a week or two and now it leaks every time. Wasting my breastmilkz Glass bottles seem to work better on it but it leaks every time. But I have to warn my breast milk and haven’t found another bottle warmer.

I don’t know where to start, we’ll first i don’t like the way it turns on you have to press it twice and sometimes it doesn’t work. Then it doesn’t work sometimes. I stopped breastfeeding and only giving formula, this warmers only works for breast milk or water, look for another warmer please don’t waste your time and money.

This warmer is great when it decides to work right. First, we had a hard time figuring out how to even turn it on and it's been an experience using this product ever since. Everything is very complex with this thing. The bottle has to be screwed on just right and the gaskets have to be placed just right and you can't turn it on until everything is perfectly in place and EVEN THEN the gaskets will decide to pop up or move around and then milk is spilling from the upturned bottle. This product is genuinely hit or miss. It was purchased for me because I thought it was the perfect registry item, but I would never purchase it for someone else. And I would never purchase it again for myself. I use it because I have it and, like I said, works well when everything is done just so but there are some serious flaws. Also, you can't clean the main part. You have to spot clean with a paper towel or hand rag. I will say the included adapters were very nice, but even assembling them onto the warmer is tricky because they also have to be "just so."

I like that it gives you the exact number of warmth which is 98.6 F, also that it has different sizes for bottles. That being said this thing is finicky. I’ll have the bottle secured, press the button, shows 0.00 and then press it again for it to start warming. Nine times out of ten it shuts off so I have to do that again. Sometimes it takes a while to secure your bottle in correctly otherwise it spills water everywhere. The 4oz Avant bottles secure the best. If you can find another warmer, do it. It’s so stressful trying to get this thing to work while you have a screaming baby in the background.

This leaks. We tried more than one and they were both faulty. If you must heat up milk on the go and you don’t want to wait for it to heat up in hot water or the microwave then it still may be not worth it to you to buy this but you may be the 1% that is okay with leaking milk for the correct temperature. It seems like way more a hassle to use than to not.

Constantly Leaks causing you to spill milk and just overall useless.
