Previously, I had 3 different levels: No. 1 was shaking like a leaf, was unwatchable. . No. 2 had a 1: 1 optics, so offered only a small field of view. Consequently, I had to constantly craning his head in order to see the desired area behind me can. No. 3 was extremely convex. Then I saw heaven and earth and everything around behind me. However, I was able to correctly identify an object only when this had come already up to about 3 feet. By contrast, the new Zefal Mirror has an excellent fit to the needs of a cyclist optics (slightly convex) and provides just the right visual field, even when changing the posture while driving. Absolutely no shaking, very good stability of the construction, easy to assemble, good quality overall impression. Therefore: full 5 stars and unlimited purchase recommendation.
