I am happy with my purchase of the Extang Trifecta Folding TOnneau Cover. It looks decent on my GMC Sonoma and works for what I need it too. I had a few difficulties installing it because I have a bed liner. I had to cut holes in the liner, so the cover would fit correctly. It obviously wasn't made for a bed liner, but I managed. It is very difficult to open and close, because the bed liner is in the way, and you have to pull really hard on the handles to open and close the cover. Apart from these cons, I am still happy I bought this product and it will serve the purpose I intended it for.
