Considering all the other screens on the market, this one is well priced. It looks great on the bike. The slight smoke tint goes well with my black bike. Just tall enough to eliminate most air buffeting.
I've bought this spoiler and couldn't be happier with it. Get the clamp-on version so you don't have to drill into your windshield and so you can detatch it and put it on other bikes.
Install took me about 15 minutes. The hardest part was getting the stock bolts loose from the bike. Looks absolutely fantastic. No complaints on my end.
