Suction Grab Bars for Shower/Tub (Porter Square Cambridge)

I bought these for my disabled husband because the product description says it can support 275 lbs. He weighs 170 lbs, and he pulled them off the wall on the first try! All others I saw say to use only for balance assistance, and not to support full body weight. I think that warning applies to these as well.

If you think you can make use of these, they're all yours. Just be warned to be careful with them.
