it's.. meh
I have porcelain slab shower walls so they are super smooth and there are no seams. You MUST apply the suction cup to a COMPLETELY DRY wall. even the slightest bit of moisture will cause it to slide with any pressure. Even with doing this, i find that i have to reapply at least every other shower. You definitely can't put a lot of pressure or weight on it, but it really is intended as a balance support and not a step. So it works alright.. but not perfect.
