I have only had this item for a couple of days but so far am really pleased with it. I fought against buying a bottle warmer for weeks thinking that it was a waste of money and boiling water in a jug would suit me fine, believing the only draw back to it was if I burnt myself (which I vowed I would never do as I wasn't that clumsy). Well, guess what, I woke up at 3am one morning and in a rush to feed a hungry baby, poured boiling water down my hand and arms. What you don't appreciate is that you only need between 30-50ml of water per use to heat the bottle, which is substantially less than the half a pint of water I was using each time by boiling a kettle. Also the heater is on for about as much time, if not less, than the time it takes to boil my kettle. It does take Tommee Tippee bottles, not a perfect fit but certainly fits in the compartment. The only modification is that you have to select either one or two points in temperature above what is suggested on the instructions to counteract the different shape of bottle. I know that pre-making and refrigerating bottles is now not suggested as ideal, however due to having a really colicky baby requiring medicine to sit in the milk for at least half an hour before she could drink it, I found this was the only realistic way of dealing with it.
