Only holds towels in place when it is full or 1/2 full
Color: 01-silver
If you are buying this for the feature of holding the paper towels in place so you can just rip one, I think you will be disappointed. Once the roll becomes smaller (and I tried changing the arm) the arm does not touch the towels. I do like the firm grip on the counter. My other dissatisfaction is the base gets water spots. Being near the sink this happens frequently. It does its job and is attractive.

Stylish
Color: 01-silver
Good sturdy stand for paper towels. Has small suction cups on bottom for stability. Good finish and good fit under the counter. Heavy base and not flimsy feeling. Brushed aluminum matched other appliances well.
