There's a potential very minor drawback, but still worth considering.

The blinding obvious (with hindsight) thing is that in order to hang under a shelf, the shelf needs the ability to host the support! I kept wondering what was stopping the bottle shelf moving over to the right, then realised it was an item on top of the supporting shelf impeding the support moving across. Ridiculously easy to fix, but it does mean that the shelf has the minor disadvantage that whatever you're storing on top of the supporting shelf will not sit flat if it goes on top of the support. It's just something to bear in mind, and it's certainly not a 'show stopper'.
