My new house has a shower stall in the master bath with zero storage areas.  (What idiot designed that?)  And the showerhead, while nice, has a weird immediate bend in it that prevents normal shower caddies from staying put.  There's nothing quite like a shower of toiletries raining down on your head when the caddy gives way, is there?  This caddy prevents that with a very clever clamping method at the top.  Yay!  Sadly, the mutant shower stall has very little distance between the showerhead and the faucet hand thingie so this caddy is too long.

Pros: I love that it screws together to hold in place.
Cons: Too long for intended shower.
