These mirrors (left and right) were budget priced and I wasn't sure what the quality would be. Turns out they have a decent finish, the mirror rotates in the ball socket well, but is still firm. The mirror size is a little smaller than a rectangular mirror, but still adequate. I did return both the left and right mirror, because I was not able to adjust them properly to be used on my bike. Because I've adjusted my hand grip somewhat back (that is, closer the direction of the back of the bike), the mirror is tilted back to far. It doesn't have an adjustment where the mirror attaches to the handlebar. If it did, it would have been perfect! I'm trying to save money and this fit the bill in every aspect accept the adjustment capability.
