Review confirmed by purchase 
After watching several reviews here for the first time, I found that this is exactly the size I was looking for. It folds up small enough to fit comfortably in my hand. It seems like a very solid product – one side is covered with rubber and is waterproof, and the other side resembles tarpaulin material. The price is a bit high given how simple this thing is compared to other similar products, but in my opinion, the build quality is worth the price.
