Excellent for one-handed operation
Color: Silver
This one-handed paper towel dispenser is very good quality. The suctions cups work very well on a clean, smooth surface. Has a good solid feeling while pulling off paper towels with one hand. You might have a slight learning curve on to how to pull correctly. Pull the paper towel only just far enough out that there is still good tension on the towel. Then pull the towel downward and close to the roll. A little practice will be rewarded with satisfaction of this product! Comes in so handy when you have one messy hand and only your other hand to pull off one or several towels. If pulling several sheets at once remember to pull them straight outward, then pull the last sheet downward and close to the roll. No fuss removing the used cardboard roll and replacing with a new roll. Assembly is easy. The assembly instructions aren't good quality but the parts only fit together one way. The dispenser will end up looking like a two-tier spoon carousel with the spoons hanging upside down. I would buy this as a gift for family or friends.

Sticks to the counter like superglue
Color: Silver
This paper towel holder definitely sticks to my granite countertop and wont move. I put it is a spot where that would not be a problem. If you need to move your papertowel holder daily, don't buy this one because you can barely pull it off the counter. But great product if you don't need to move.

works great
Color: Silver
I went through several towel holders but they did not unroll the towels smoothly. This one’s does. You can tear the paper towel off without a bunch coming undone. It’s very sturdy. Looks great by our kitchen sink. Only issue is if the A/c hits it in unravels, so we had to move it to an area where it was not hit by the A/C. Simple fix.

Works like a charm
Color: Silver
Pricey for a towel holder, but a great value for the money. Like everyone else, I’ve tried all types of towel holders that didn’t work or were tricky to replace the rolls. The ear type that have two spring loaded arms to hold the roll, if you pull too hard the roll pops out and the towels go flying. The type that has 2 arms and a rod that goes through the roll. Pain in the #$@ to detach and reattach for roll changes. Slip on type with a post and silicon fins on the post to hold the towels. Not good for jumbo rolls and the other rolls fits on loosely and sometimes a simple tug to detach a towel gets you a handful as it spins away. So I saw this one, hesitated at the price, but based on reviews decided to give it a spin, ( sorry about the pun). It holds the towels firmly thanks to the springy fins attached to the center post. Sized for all rolls, even the jumbo. Stays anchored to the counter with the suction sups. And, dispenses towels with a simple tug with one hand. No need to hold the roll, this baby does what it says. I like the sleek look and the stainless steel finish. As to the cost, if I had bought this one instead of all its failed predecessors, I would have saved money. Buy it, you won’t be sorry
