I've tried the Italian road bike mirrors and wouldn't get them again. On both of my bikes, the glass has fallen out, likely due to me trying to do minor adjustments on them after setup. These mirrors are wrapped with your bar tape, so be prepared to remove your tape to replace or adjust. I bought the Sprintech mirrors a while ago and love them. They fit into a plug that replaces the bar end, sort of like a ball and socket joint. They can be adjusted and can be replaced if needed without unwinding tape. Mine is very positive and I've not needed to adjust at all after initial setup, but I could if I needed to. They came as a pair, one for the left bar end and one for the right. Didn't install the right one, but now that I see how unobtrusive it is, I'll put the right one in as well.
