the suction cups last and work well. Only thing is, if you have it under a basking light, the traction strips will sort of come up off the plastic at the curves. I just peeled it off and it's fine. Didn't leave sticky residue and the turtles don't care. Without the traction strips, it gets less algae on it anyway.
