I never write reviews, but thought this product deserves my opinion.  We have a walk-in shower and didn't want to hang a towel rack inside or outside of the shower. We purchased the 3 and 5 lb. hooks to hang towels, wash cloth, and scrubber.  The towel hooks aren't close to the water, but the other 2 smaller ones get wet every time we shower.  We put them in 4 years ago and have never had any issues.  They are still hanging and absolutely Love them. Now anytime we want to hang anything - it is with 3M Command Hooks.  Thank you for a great product!
