We bought this after originally buying the bottle warming flask. We use Tommee Tippee bottles and found that too slim for the bottles (we actually got a bottle stuck in the warming cup and had to cut the cup to get it out!). I know this one really is for food, but if you're using Tommee Tippee bottles I recommend this one instead. Takes the worry out of having to be somewhere that would supply hot water to heat your baby's bottle. You can be prepared and use it anywhere. We even used it during the night for the night feeds. Just a quick tip... to keep the water hotter for longer, pour in boiling water, leave for 5 mins, tip out then pour in more boiling water and seal.
