I only had mine 3 or 4 weeks and I love it! Installation was a challenge for me: I was by myself and have "tennis elbow" in one of my arms. Anyway, it took me more than the advertised installation time but I got the cover installed evenly. To do that, I had to loosen all the bolts holding the brackets, lay down in the bed, reposition the cover several times with my arms and feet until it was perfectly even on both sides and then I tightened everything. It has been like that since then and no a drop of water inside. Tip: follow the instructions from the manufacturer to the letter; the specs they give are really what you need to respect (17", ...)
