Bests & Worsts Reviews from Amazon

I purchased this as an assist for my 93 year old mom as she steps out of the shower. It was attached to a clean, dry, wall. After the first 2 days I noticed it was a little loose, so I reapplied it. It feels very secure when its attached. However, for some unknown reason, it simply popped off the wall around 10:00 PM one night. Both of the tabs used to secure it to the wall were in the open position as it lay on the floor. 5 hours earlier it appeared to be attached securely. I am now nervous to continue to use it, but will see if it stays on the wall. Update- After 5 days, I found it on the bathroom floor and it had not even been used. I am returning it as I would not trust this to do anything but fail. I would give it zero stars.
