Aside from the funky smell--which seems to be part of every pair of Reef-brand flip-flops I've ever had--they're not bad.  Couldn't care less about the built-in bottle opener, but I ordered these because a comment from a Reef rep suggested that these had more heel support than the model I was originally going to order.  That seems to be true, and once I get them broken in I think I'm going to like them.  Reefs are the only flip-flops I've ever had that have the funky burnt rubber smell, and I have no idea why.
