I bought without any reviews, but for the price, I decided to take the risk. I haven't used it at the beach yet, but I wanted to add some more information here asap. I included a standard tote bag for size reference.
I was concerned that it would be super thin, but it feels like a much thicker camping tent material (ripstop) and water beads off of the top AND bottom (the storage bag too). Wet grass was something I was concerned about because the description didn't mention this at time of purchase.
Steaks are plastic, so unsure how durable they will be, but you could replace by tying metal ones easily. The loops are elastic, so that could help with keeping it down even with people stepping or shifting slightly when laying or sitting on the blanket. The pockets seem to be pretty generous, so you could fill them with a good amount of sand at the beach.
4-star rating for the unexpected high quality, untested plastic steaks, and for not having used it yet.
