I bought this after using a couple of cheapo Chinese mirrors and not being too impressed. I've used it on the commute for a week now and I'm mildly impressed. It fits the swept-back bars on my Ortler, but I think it would fit most types of flat bar. Bought off eBay for £10 and used for a week on my day/night commute.
Good points:
Overall, a tenner well spent - so far.
Good points:
- Great field of view with the large, cats eye-shaped mirror
- Decent build quality
- Easy to fit once assembled
- 3-way adjustment (but see below)
- Needs to be assembled (not that tricky, but still)
- one of the fields of adjustment relies on friction between two planes and this cannot be tightened by screws like the other two planes. The friction simply isn't enough to stop it moving when going over bumps.
