I tried a helmet-mounted mirror, but it attached with sticky tape, and it just didn't stay on. It also vibrated a lot more because I guess my helmet vibrates more on my head than my glasses do. The Take-a-Look mirror mounted on my sunglasses just doesn't move. And no sticky tape to get de-stickied over time. The mounting mechanism is wire and couldn't be simpler. It can be removed and moved to a different pair of glasses if you wear more than one. And, it came highly recommended, that's why I tried it, and I love it, as stated above.
