I'll add more detail later (we're travelling so I haven't had much time to keep up lately) BUT I recently put the
10
x 13 YUEDGE Tarp through a bit of a torture test, and the results were a little disappointing. Although to be fair I did say torture - the "test" was covering a mattress on top of my car for 350 miles of mostly highway driving, some of which was through very heavy rain. While the fabric made it through without any obvious issues, the stitching and the silver finish (which AFAIK is what they added to make it waterproof) appear to be rather fragile.
It still will probably be fine for occasional use, but I would expect problems if you use it in really windy conditions or have anything rubbing against the inside surface. I would be very hesitant - due to the weight and the increased chance of failure in harsh conditions - to take this tarp on any serious backpacking trips. However, as long as you treat it gently and don't expect it to last forever (and keep it INSIDE the car while travelling...) it could still be a good value for backyard or car camping.
