I've had mine for about a month; put it on three weeks ago for a 1½ week-long road trip through New Mexico & Colorado. After the trip was over, I took it back off (and stowed it in the cover that comes with it). I wouldn't have bothered to take it off, if it weren't so easy to do.
Anyway, we took a top-down freeway ride last weekend, and my better half was unhappy with the increased wind turbulence with the windbreak removed.
Bottom line, it does its job well, looks great, and mine is going back on the next time I have the top down.
