Great for short people to see and retrieve spices from upper shelf! Holds a lot of weight easily!
Color: 2-Pack Black
These spice racks were very easy to install in my cabinets. Actually, I have only used the adhesive, and they are holding all of the weight of the spices without any issue! These are remarkably heavy duty. I am short (5"3") and most of the second shelf is not really very useable without a stool. I can pull these out and turn the racks making all of them visible and easy to reach! I have two and I'm seriously considering ordering more! It makes organizing a breeze too!

Beautiful, easy assembly.
Color: 2-Pack Black
Looks great, easy to assemble. Just a little narrow, wish I would have ordered a little bit bigger size.

Easy to assemble but overpriced for what you get
I like this rack. Especially because it was very easy to assemble. Although it is only suitable for one size spice bottles. It wont hold larger or taller spices which was a small issue for me. But overall i found it good quality. But i think the price is a bit overpriced for what you receive and for the functionality
