I have a CVT because it was available when I was picking up my tent and I had some store credit. The overall design is pretty simple, 4 extendable poles and a sheet of canvas. The "hinges" at the truck end of the pole are plastic, which might be a long term durability issue, but hasn't caused any issues in our 2 years of using it. The only time we've had a problem was getting caught by a severe wind gust during a thunderstorm. That twisted and bent a couple poles. We were able to straighten them out, but it took some work. I think all of the awnings are probably the same in that regard, if you're expecting anything other than a light breeze they need to be guyed out and staked down...
