Review on Enhanced Visibility & Customizable Motorcycle Windshield Extension by HOZAN - Compatible with Majority of Motorbikes by Sheppard Priest

Seems well done. As others have said about this and similar models, the plates move when the screws are tightened. Just hold them tight as you put them on. The disc itself has significantly more distortion than the factory disc, but can only be seen for a short time. It can be tilted while riding and helps reduce the wind blowing into my helmet. The quick release must be replaced with a normal screw. It's not very easy to tighten. And you need to loosen the screw a little to turn the lock knob if you want to move the screen up or down. The handle fits into a groove and will not lock unless inverted. For the price, if it doesn't break, that's not too bad considering the next highest price is around $120.
