I have 3 Rollei B35's and love them. Like anything else, once you're used to it, quick and easy to use. I don't bother to retract the lens, because I carry it in a small case with a pocket digital, a 2X ND, and several rolls of film. I find the 40MM lens is a good 'middle of the road' choice. The negs are more than sharp enough. No battery. They can't be as useless as somebody is making them out to be, considering one in good condition commands a pretty decent price, which means people want them. An excellent small camera.
