Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.

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!
