Useful works as intended
They're not to bad. They're definitely not motorcycle mirrors, but they certainly help. They look pretty cool too. I get comments about them all the time
there are many mirrors you can get but this one I have found is the best. you can get it setup the way you like and tighten it in place; allowing you to have a well positioned mirror even on rough roads or after a long ride. I find many mirrors need constant adjustment making them rather useless for a quick check behind you. these do wonders.
