Bests & Worsts Reviews from Amazon

Purchased this for (mostly) sunny Southern California weather. I'm a student so I had no choice but to keep my new car outdoors, and I didn't want it looking dirty all the time. For reference, I was using the cover on a Black 2011 Nissan Altima Hybrid (within the size specifications for the cover, but on the lower end.) Unfortunately, I've been extremely unhappy with this product. There are several reasons for this: -First, and perhaps most importantly, the stupid thing won't stay on for more than a few days at a time. No matter how I try to secure it, unless I use a hook or something at the bottom it can and will come off. This happens especially often during inclement weather, but even when it's sunny outside the thing still comes off somehow. -Second, it is neither waterproof (not advertised) nor "water repellent" (advertised). After 30 minutes of rain, my car is as soaked with rainwater as any other car in the lot. -Third, it DOES NOT keep dust out very well. In fact, the cover seems to make dirt and dust collect in visible streaks at different points on the car. It's probably slightly cleaner than the car would have been without the cover, but the dust is more visible because of the way it collects. The two stars is generous, in my opinion. I have stopped using the cover because it has caused me more trouble than it's worth.
