Mirror good workmanship, easy to install and inexpensive. Valuable for those who do not want or can not mount a mirror at the end of handle, mandatory fitting for the majority of mirrors available in the market.

However, with some mirrors, the bulge is such that it seriously and dangerously false appreciation of distances. Left to choose between excess convexity and its absence, I prefer the choice of gravidus mirror, I'm happy to have found.
