I have 2 of these. Great tarps for the price. They seem well made. The seams are taped, and I haven't had any leaks.
One thing that I don't like is the stuff sack. It's the same material as the tarp, which has one side silicone impregnated, which makes it waterproof. The downside is this makes the inside of the stuff sack "sticky" and the tarp does not slide in well. I have to fight with it.
Otherwise, great rainfly.
