Needs better hardware
Color: Natural, Size: 36 Inch, Color: Natural, Size: 36 Inch
Shelf looks nice, but it’s a heavy piece of wood. The hardware that’s included is not strong enough. The hardware broke and the shelf fell the first day.

Shade for trees
Size: 4 Panel, Color: White, Size: 4 Panel, Color: White
Going to try to use these to shade my trees from the late afternoon sun. I just put them up so we will see how they do! I purposely bought the ones with curved feet since the flat feet wouldn’t have been sturdy on the rocks. Was easy to put together and they look nice. Debating the 6 pack so I can put two on each tree with the connectors.

Be Cooler About The Packaging and Instructions.
Size: 4 Panel, Color: Black
This packaging is TERRIBLE.
The "instructions" are TERRIBLE. They were just a single sheet with minimal info, SHOVED into the box randomly. Could've folded it flat and slid it in there. Both times I ordered this, I had this exact same experience.
Good thing I've put together tons of furniture and toys over the years.
I'm sure older people would have a hard time with assembling this.
At least it's light to move around without trouble, and blocks SOME light. Does not block the flood lights outside my building, which shine into my living room, but oh well.
