Free Mini-Screwdriver + microfiber cloth? Thank you
Color: Gold, Material Type: Stainless Steel
100% worth the purchase mainly for the little screwdriver (a real one, just small) and microfiber cloth included. As long as you install it correctly it all holds together very well.

The quality of this product was excellent. Very sturdy. Easy to assemble. Just what I was looking for. When getting the paper towels, the base did not move all around. Highly recommend for the price.

Lightweight but I like it
Color: Black, Material Type: Stainless Steel
Honestly fantastic for the price. It's just heavy enough to not get yanked around. It's pretty. And it has not looked like it has any wear or anything yet. I would recommend it. Especially for the price. If you want something a little bit more heavy duty I would definitely go with something else but I've had no issues
