I have bar end mirrors and love them, also got some block off plates (chrome) to match.
You can kinda see the bar ends, I really like them, but they are cheap and are cracked in the housing. THey still work, but I'd like to have better ones. They are convex, making things behind me seem clearer, and closer, which I like. The regular circular ones are just regular mirrors and make things seem small in the mirrors. thats my honest opinion.
