If adjustable arms are important to you, DO NOT BUY THESE! I need adjustable temples (maybe my head has an odd shape). In all other glasses I've seen, the adjustable temples are characterized by the fact that they rotate so that the glasses fit your face correctly. They claim to be adjustable temples but all they do is pop out (1/4 inch facing you), misleading description and useless to me. However, if you don't care about adjustable temples, you might be ok, but to be honest, they're no better than those that cost 4 times as much.
