Review on SONGMICS 2-Tier Spice Rack: Organize Your Kitchen with this Freestanding Metal Shelf for Jars, Bottles, and Cans - Holds up to 88 lb, 15.7 x 5.9 x 10.4 Inches - Silver ULGR21SV by Stephanie Fields

The processing of this device is acceptable. Assembly was easy and all parts were included. It doesn't wobble when you first assemble it. My spices are in jars the same size as the ones in the supermarket. Because each can is just standing on two metal brackets that run across the shelf, it doesn't take much pressure or pressure to tip one or more of them. Luckily the wall keeps mine from falling out from behind. This will likely work much better for larger diameter containers or smaller boxes.
