We use the MAM bottles and love them. I combined breast and bottle for a while too before switching over to formula feeding completely and it worked out really well. DD took to them nicely - we tried Tommee Tippee bottles first but hated them. (She would quite often refuse them and they just dribbled down her face every time she fed. Also she was quite windy after feeding from them but not as much with the MAM ones. That was really important as she had silent reflux.)
They're really easy to clean as they come completely apart, and also, the self sterilising is really handy, no need to take a sterilising unit if you go away for the night (or longer.)
The only negative is that you have to ensure you've put them back together really meticulously so that you don't get leaks in the bottom valve (particularly important if you need to cool a bottle down in cold water.) But that's a small down point, and you get used to making sure it's all screwed together properly.
But all in all - big thumbs up from me (and baby Sofia.)
