I got a couple of these  to use as towel hooks. We wanted to give them a try as replacements for a towel bar. In part, I wanted that because our towels don't necessarily end up folded to neatly hang over the bar.  This eliminates me obsessing over that :). Pros: I feel like more towel area is exposed (not folded under) and our towels dry pretty quickly.  They also take up less space and are a breeze to install. Super templates included in all of the Moen Align products. Con: since the dip in the robe hook is somewhat shallow, we've had to learn how to fold a small lip of our bath towel over so that our towels don't slide off. Minor. 
Besides the great templates, these hooks are also attractive (we have matte black) and substantial (approx. 2-3/4" from wall & 1-1/4" in diam). They add to the contemporary, spa-like atmosphere in our bath.
