DAILYLIFE 19 Inch Heavy Duty Shower Grab Bar with Strong Suction Cups - 300lbs Weight Capacity Safety Handrail for Seniors & Elderly - Non-Slip Bathroom Assist Handle for Bathtubs & Showers (Silver) - Perfect for Fall Prevention & Mobility Assistance in Wet Areas

I have hip arthritis and need some place to lean when I get in and out of our 70-year-old tub/shower that has be resealed with a vinyl/plastic. We have had the 17" handle installed for two months now under the bathroom window. Being very careful before using it and checking each time, I have not even removed it once as directed to reapply. I think if you used an elephant to pull it off it would remove the tub wall and the handle would remain attached. ;DWhen I climb out of the tub after showering, I need this handle on the right to lean towards the left as I hold on to a great little guard rail and lift my left leg over the tub rim.. A month later, I purchased the smallest handle and installed it under the shower head area to use when lifting out the shower sprayer. That one, too, works great. About the latter, after a month I am beginning to see a little of the red indicator but the handle remains solidly attached. I will be removing it and reapplying as directed this week, however. I suspect that that part of the shower wall changes temperature and gets wet, affecting the suction just a little.Installation: I cleaned the wall surface with rubbing alcohol before applying the handle. It went on smoothly, but if you have problems with putting pressure on your hands, ask someone for help. You really have to push the latch hard, because it seems to compress the material (a soft very thick vinyl-like material) to create the vacuum. It's amazing. By the way, there's a review here from a large gentleman using it to lift himself out of the tub itself. It sold me, and he is quite right about how strong these handles are. Remember, the surface cannot be one listed as "do not use". It needs to be a smooth surface like plastic.I waited half a year before buying one. Don't wait as it is really a good product and has helped me navigate the tub immensely. Even my strong, muscular adult son wants one for his apartment so he doesn't have to touch a yucky wall.The handle is well-constructed. The bar in the center is very short on the small. I have small hands and one hand just fits. Plenty of room on the 17 inch (the one that has been up the longest and shows no signs of de-vacuuming.) I'd ask the manufacturer to revisit the handle itself...it consists of horizontal grooves very close together intended to make it non-slip. My grab bar, which is only enamel paint is less "slidy". Something about those grooves when they are wet make your hand slide back and forth, so I dry it with a towel before exiting the tub. Nothing dangerous but does not feel grippy.
