When I first brought my baby home I tried this bottle warmer and decided early on that it was not going to work. I tried warming up only a few ounces of formula and it took over 20 minutes! When a baby is crying for food this is not a good product to use.
I found it a lot more useful to just put the bottle in a cup of hot water.
The warmer does not have a timer or an on/off switch. Each time it is used you have to plug it up into the wall. I just did not find this to be a good product at all. I still have it but I'm not sure if I will ever use it again. I have not tried to warm up baby food with it but I would assume that it does not do any better with that.
I had high hopes that this product would help me save time with bottle warming but the old-fashioned way is 100% easier!
