Verdict:
1. where it hangs want (I took two at different heights like that each his own)
2. suction system allows to put a lot of weight in that it does not move (once it is set, good luck to remove it)
3. plexi allows to clean through the shower head above (and it does not rust unlike those made of metal)
4. no need to make holes to fix (because when one is preferred tenant avoid holes)
5. Price is widely affordable (and believe me I've seen models)
Would I recommend to friends? Yes quite. Besides, it is already done!
