I originally got one of these as a sample when I received a sample bag from my doctor's office. I used to use Tommee Tippee bottles, but I like that these aren't as wide (fat) and fit better in regular cup holders, etc. The only thing I didn't realize is they have 4 nipple sizes, and the numbers on the nipple are not the same flow as T.T. bottles. So just make sure you know what number (flow) you need! ..
