I was not sure about this product when I was researching travel bottle warmers. However, after using it for a couple of outings, I am so thankful I took a chance on it. I actually bought 3 more, so we have 4 to take on longer trips. It warms my baby's milk in about 10-15 minutes, if you want it warmer it will take longer. It just requires a little planning, not a big deal to me since her bottle warmer at home takes about the same time.It does not require power, I wasn't sure I would like this, but I LOVE that feature. Perfect for hiking, camping, family adventures, long road/plane trips, etc.Boiling it to reactivate it isn't a big deal. I just take care of it at the same time as washing bottles. Easy peasy.I'm also sure we will use these once she is on solid food and we don't need it for bottles anymore. It is a pretty versatile product.NOTE: I use Natursutten bottles with this which are glass and narrow. I am not sure larger/fatter bottles would work with this.

We have used this several times to warm up my grandson's bottles. We decided to purchased another one because sometimes we needed another bottle warmed.

Heated up at 7am and was still warm at 1pm. So glad I took time to search and read reviews. Bag doesn't fit 2 bottles but does fit 2 Kiinde bags with 5oz each in them. So i just packed my 2 bags on the go and filled bottle when baby was ready for it. Strongly suggest this for parent on go with baby and won't be able to get to any plug in type adapter.

Love this product. It warms baby bottle in 30 minutes and maintain it warm for over an hour.

Best item I ever bought for our first child. I could warm bottles for her anywhere, anytime, anyplace. I can't recommend anything more highly!!
