I am not hopeful. All of what holds them together is plastic. Joints. Zip ties. I can't imagine it will hold up in direct sun. I put it together inside and then tried to carry it outside. Turns out, it can come apart when you pick it up, even when the shelves are empty. Assemble it where you want it, and never move it. The hilarious part is that the directions say "when using the product, ensure the ground is flat". Since all the corners push together to varying degrees, I can't get the shelves themselves level enough to sit flat. It's not worth the hassle of returning, but I definitely will not be purchasing them again.

My wife and I were so excited to have these shelving unit until we tried to assembled them , one of the brackets was incorrect , therefore ; our mission was delayed

This works as a practical and pretty garden shelving unit. I have it on my front porch for my shade plants. It was easy to assemble in under 15 mins. Very good size. Downside the shelves are kept together with zip ties, so it is not as sturdy as it could be. I worry about moving it. But it holds my potted plants well.

These rack are just okay for small items .. I wanted to add them in my greenhouse but my pots were too heavy. If you have small pots or light ones these would be great. I had to end up using them for my little online store and they worked just fine

The rack is not as sturdy as expected. The grade shelves are adhered to the already unsturdy structure with zip ties. Worried this will not hold well. I may have to use these to store something else than originally planned. Not necessarily a rack i would at this time recommend if you have heavy items . I’m going to reserve my opinion until I actually see what it will hold.
