Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.

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.

Looks great, easy to assemble. Just a little narrow, wish I would have ordered a little bit bigger size.
