Review on 🚿 Efficient Wenko Bari Vacuum-Loc Corner Caddy: Adhesive Shower Shelf and Shampoo Holder, Rustproof Chrome Steel, 12.4 x 3.3 x 8.7 inch by Joel Gumbiner

I bought three of these in 2017; one 6.7" wide, one 10.2" wide and one 20.5" wide. I installed them on our smooth fiberglass tub surface. They are great. The large shelf holds four liter bottles of my wife's hair products. Mine Wife leaves them on the shelf when using the pump dispenser for the bottles which gives the shelf more strength.After about 18 months one of the shelves came loose.I reinstalled it with the vacuum pump provided and it was as solid as ever.Now I have a note on my calendar that once a year I have to use a vacuum pump on all the shelves. We have well water and a water softener. The water contains traces of salt. Three years later the shelves showed signs of rust. I took them off and painted them with silver spray paint. I then gave them a coat of Rustoleum Clear Automotive Wheel Coating. They don't have a glossy finish but still look good. Looking back I wish I had them with me when they were new sprayed with a rim paint. If you have a smooth surface they will work great.
