Easily assembled.
Size: 3Pack of 5 Tier (Not included planks)
Easily assembled, seems sturdy and built to last. Once attached to wall seems even sturdier than expected. Anchor pieces included but I choose to find studs to anchor to.

Good but misleading size
Size: 3Pack of 5 Tier (Not included planks)
Sturdy set for shelving. However dimensions are misleading. Not sure if they sent the incorrect size but the vertical distance between shelves was 11” and that’s without the shelving installed
