I've had one for the past six years and am generally pleased. There are tradeoffs and drawbacks, as with anything else in this world. It does tend to have a very slight leak near the latch. If you venture up into snow and ice country, it can be difficult to retract and more importantly, impossible to open if water gets into the lock and freezes. On the other hand, it is very sturdy and protected the contents of my truck bed pretty well both from theft and from the elements. The lexan slats can crack; I've had a slight crack in one of them but not all the way through, so cosmetic impact only. Very simple to remove and reinstall once you have it installed the first time.
