CONSTRUCTION: I can vouch for the durability of these things as mine fell off I was riding (my fault for not tightening the bolt enough). One minute it was there, the next, gone. Retraced my steps and saw it in the middle of the road...flattened. Obviously, something had gone over it, but, surprisingly, the glass was OK. I got it home, put a new bolt in it and refitted (with Loctite). It's a bit scarred but I think it adds character.
INSTALLATION: Was a pain.
The biggest problem I had was drilling the bar-weights out as the material used is really tough. This problem would exist with any bar-end mirrors. Other than that, no problems.
PERFORMANCE: Poor. They're 60mm across-what do you expect? That said, I only use them whilst stationary, to keep a eye out for anything that's bearing down on me from behind. For that, they're great.
OVERALL: Setting them up is a pain as it takes 2 allen keys and you can't do it whilst moving. You can see very little out of them but, for my purposes, they're ideal. Look great, feel great, excellent quality.
If you're the kind of person who needs to see as much behind as in front, look elsewhere (maybe at the bigger Oberons). If, like me, you only use mirrors to do your lippy in, with the occasional rearward glance, they're great.
