Rode with the new windscreen for 200 miles. I'll keep it short.

Measurements:
OEM - 3 5/16 "
New - 4 "

Didn't weigh it, if somebody wants that info I can do it. They're both light pieces of plastic. Has a good fit. Had to reuse the rubber mount pegs from the old windshield.

Comparing the highway rides, noticeable change in the wind deflection. The wind hits about 2-3 inches higher on my helmet (5'8"). This can be a pro / con. Pro, less wind. Con, hotter helmet. Previous windscreen hit right under the helmet. New one hits somewhere on my visor. This is going 80+ mph. Air flow is smooth.

It's a noticeable change. For the money, I think it's a fun thing to experiment with. The construction is solid; I wouldn't worry about it breaking. The bubble doesn't seem very large, but there is an effect. Maybe a Double Bubble has a bigger bubble, and that may be what you're looking for. For me, for the cost, the value proposition is there. And it looks cool!
