I've had mine for a couple of months. They're great unless you need to get out really quick and don't have the wherewithall to pull your feel out in the right direction - something I had to get used to after riding loose spds for two years. I've done a couple of supermans with the bike

which is not fun. But otherwise, they're great - very easy to get into once you get used to them - and they have a great feel.
