Changing Lifestyles Safe-er-Grip Drip Dry Portable Drying Rack, White with 3 prongs (2-Pack)

I purchased two of these. With one of them the three drying rods spin unless the drying items are carefully balanced; the other is stiff and holds pretty much where I position it. Also, these work great in my fiberglass shower stall, but I tried them yesterday in my tiled bathroom (4"x4" tiles) and both of them fell down after about three minutes--just as I was finishing washing my items and getting ready to hang them, fortunately. I slightly dampened the suction cups and tried again, with the same result. They stick solidly in the shower stall, though, so I am still pleased with my purchase.

Great for suits and cover ups but I can’t get it to hold my towels - they are thick but not out of the ordinary.
