I ended up returning my Italian Road Bike Mirror recently. The view is more like a the left side view mirror in a car (i.e., it's not a rear view mirror). But because it uses a convex (or is it concave?) mirror you can't see much past about 1/2 block back unless you stare at it. It's fine for one thing - riding on a shoulder or bike lane and keeping track of cars passing you. It's not hard to install but I had to rotate my bars forward quite a bit which placed my drops is a less usable position (plus I had to reposition my hoods.) It might be fine in a quiet rural setting but I found it nearly useless for Los Angeles. If you buy it on ebay the vendor has a 30 day return policy and it only costs you return shipping to try it out.
