Anybody use those suction cup Grab Bars they now advertise? I saw them briefly on TV a while ago and can't recall the name. They were white with big suction cup on rear to hold them to tile, fibergalss showers etc. Does anyone know where to order them? Cost? etc

Do they work (hold)??? I have a prefab fibergalss tub/shower and cant drill into the walls. Well, I could but would need to hire a contractor to reinforce the wall behind the tub wall since the studs are so hard to find... I thought this might be a cheaper and easier alternative.

Opinions Pro/Con from anyone please. Thank you in advance
