I have one on my 06 tacoma. bought it used off craigslist and its still in great shape.
like most people, it fits my needs perfectly and is SUPER easy for one person to go from having a canopy, to not having a canopy. people's main gripe with them is that you cant lock them like a hard shell..well if someone wants to get into your hard shell for valuables, theyll break the window, then you're out that much more $ to fix that. being able to just fold it down and out of the way is also super handy for me when it comes to picking up something at home depot that wouldn't fit under a normal canopy. fit and finish is amazing, and it seems to be holding up very well.
i love it for hunting seasons, both early and late. keeps the dust off gear early season, and water off late season.
my only complaint is the rear window is cloudy and hard to see out. when im towing my boat, i roll it up so i can see better for launching and retrieving, other than that, i'll definitely own another on my next truck.
