good visibility, no hindrance

Had 2 other (round) bicycle mirror (of Proline and BOOM), and this is from the perspective of her so far the best. The other two have either the handle portion Disabled (Proline) or offered as no clear picture (BOOM).

1 point deduction, because they allow companies no longer runs around the wheel can put up to repair (but could in the other two mirrors do not), and because he (probably because of the larger area a little more than the other two tends to fog - wipes one but slightly off the water).

Addendum: After almost 2 years of mirrors is still intact, even though it has gone through many falls. That was with the other two do not, of course - for example the Cyclestar (BOOM) has often broken's times in his 2 parts.
