Looks good works great
Item Package Quantity: 1, Color: Black
This paper towel holder is simple, sturdy, and works exactly as it should. It holds the roll securely and makes it easy to tear off sheets with one hand. The design is clean and attractive, so it looks great on the countertop without taking up too much space. No assemble required and a great value overall.

Functional and beautiful!
Item Package Quantity: 1, Color: Silver
This towel holder is a fantastic find! It is always great when a product exceeds your expectations and this towel holder is exactly that. At first, I was not sure if the price was worth it but when I opened the box, I was pleasantly surprised by the quality of the product. It is solid and well made with a heavy base that makes pulling paper towels with one hand a breeze. The mandrel is thick and provides excellent rotational ability. Overall A+. I highly recommend spending a few extra bucks on a functional piece that enhances the overall appearance of a kitchen.

Looks good works great

This is a nice paper towel holder. I keep it on my counter and it looks great. Its easy to use although I haven't tried it one handed. I like it and I think it was a good price. It was very heavy and works great.

Great and Useful
Item Package Quantity: 1, Color: Silver
This is a great and very functional paper towel holder. It is heavy enough to stay where you put it and the tension arm holds the paper towels really well so that you can actually tear one off with one hand. There is a ring on the top of the holder so, if you have two hands free you could hold on to that for stablizing the holder but it really isn't necessary because it stays in place really well. The only advise I would give is to be sure that the next paper towel on the roll is a bit past the tension arm so that you don't have to adjust the roll to get the arm to hold the next towel. This is a great invention and I'm so happy that I have found it.

Love the black, it matches my kitchen well. Very sturdy, more so than the Simple Human one that the tension arm broke. A very good product.
