Warmze Refill Warming Wraps, Black/White, Small, 4-Count

These worked great. I got the warmer kit and used them with the sleeve that came with it but you could also use the warmers in between a pair of socks. I used them to keep water warm and then added formula at feeding time. I used 4 warmers over 2 days at theme park where it was already warm outside. It took about 30 mins to make room temp water warm. When I left it on the bottle for several hours it got hotter than I was comfortable with so I had to let the bottle cool a bit before feeding. Each warmer stayed warm for about 7 hours.

I couldn't find anything else out there like these. It does take time so as long as your prepare they work great! They also last a while so you can reuse in the same day.

I would no suggest buying these to warm a bottle from scratch, but work great to keep a bottle warm if traveling. My son is picky about bottle temp. I wrapped the water filled bottle in one of these after it was piping hot. Then inserted in bottle carrier we have already and kept it the right temp until we needed to add formula and feed.

This is live saver when you travel in car or flight. But dont know why do they take so long to deliver the large refill pack !!!

It was a life saver on a 9 hour flight to Europe! I was able to give my little one warm cereal, warm milk, and Camilla tea. His stomach was happy, and so was I.Other moms on the plain asked what under that beautiful bottle sock decorated with owls was, and I shared my secret with them. I will never forget their reactions! One mom helping another mom...to be free and happy when on the go...

My wife and I love this product. We are on the go a lot and this allows us to do that. It's not a bottle warmer for every day use, but it's small, fits in the diaper bag and is always there when you need it.

I bought this product for the second time because the first time they were amazing. Then this order came and I found myself to be disappointed. The stickers are hard to peel off AND they don't stay heated as long as the first order. Very disappointed but MAY give them another try if I order again, because they do come very handy for travels and on the go's.

I love the warmze warm ups. They are a little difficult to stretch over the Tommee Tippee bottles, but it can be done!
