I have one and it is absolutly worth the money.
Tried others but either to much buffeting, didn't stay in place, or looked ugly as sin.
On the recommendation of others here took the plunge and would not ride with out it. it is great. BTW: I called the company before I bought it and not only did I talk to a person, I got a knowledgeable person who answered all my questions. I would suggest doing the same.
