Functional and Good Quality
Color: 01-silver, Color: 01-silver
I give this SMARTAKE paper towel holder 4 stars. Overall, it's a very good product that I would recommend, but it has one minor drawback that takes away a star.
The Positives
Quality and Stability: The holder feels good quality, and the material (steel) is sturdy. Once placed on the counter, it's stable and adheres well to the surface.
Assembly and Use: It was easy to put together; just read the instruction manual. I confirm that it works well even with large paper towel rolls. Furthermore, it's not difficult to change the roll at all.
The Drawback
The only problem is the small mechanism that's supposed to adjust and hold the roll (the piece that prevents it from twisting too much). As the paper gets used up, this piece doesn't do its job properly, and the paper unwinds more than it should.
Conclusion: If you're looking for a modern, stable, and well-made holder for your kitchen, this is excellent. Just keep in mind that the adjuster isn't the best, but other than that, it does its job perfectly.

Classic holder keeps paper towels in place in a breeze.
Color: 06-bronze
This classic paper towel holder works perfectly. I had constantly unrolling paper towels in the breeze. This holder keeps everything in place now. So nice. Plus, it has a sleek, uncluttered design. I’m very pleased.
