So I have tried several of these rugs, both the ones made specifically for cleaning aquariums and others marketed for wet situations, and these Cobalt rugs are simply not worth the money. They absorb about as much as a regular bath towel, but the water stays close to the surface and will run off when you attempt to pick up the rug. It needs to be hung up by two corners to dry completely. It does not dry efficiently just hanging it over a rod in the shower or by laying flat. Funny, but chewy sells a dog drying water grabber towel that actually performs better than this thing.
My wife is so happy that we use these rugs instead of our bath towels! Not only saves the floors but easy to wash and reuse. Holds any splash that I can dish out! Very pleased with the purchase.
