I gave it the road test today and this window is fab !! It came from superatv.com. It has a rubber seal that goes up against the roll cage that completely seals off any dust from getting around the sides. The ride was so much more dust free making the trip much more enjoyable. Additionally It seemed to block out some noise from the engine in the rear. I noticed there was not as much hot air flow from the shift lever up in the cabin,, my theory is that the air restriction is also restricting hot air from the tunnel entering the cabin. I ordered the tinted window to keep out the sun's rays but when dust collects on the outside of the window , because of the tint it makes it a little harder to see out the back thru the rear view mirror.
