I've had mine a long time. Probably 4-5 years or so.
Ease of use- 10. Once you figure it out, I can have the windows in and out in under 5 minutes.
Watertight - 4 mine leaks around the joint above the roll bar. Nothing is there to fix, just a design flaw. It's a pretty steady drip on my shoulder.
Looks- 10. Still better than the trektop IMO.
The only thing that has broken are the little plastic clips to tighten the rear straps. I used chain quick links and have never had a problem again.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.
- Samuel Adams
