It's a quality product; sturdy and dries thoroughly overnight hanging it over the grab bar in the shower.
I don't know if I'd call this a weakness, but due to being bed-bound, my husband's skin is fragile. The mesh pattern left some markings on his lower back area the first time we used it. The second time, we lined the sling with a piece of sheet with a cutout and there were no markings.
My husband has had Parkinson's Disease for 17 years and became bed-bound after an upper respiratory infection.
