Let me start by saying - these shelves are BEASTS. I've used them in my garage for 3 months now, storing everything from power tools to car fluids, and they haven't even blinked under the weight.

The assembly was shockingly easy - no tools needed, just slotting poles together. Took me about 15 minutes while watching TV. The wheels with locks are a game-changer when I need to rearrange my garage layout.

What surprised me most was how sturdy the wire shelves feel. I've got about 200lbs of car parts on one shelf and it doesn't sag at all. The black powder coating has held up perfectly against oil spills and garage dust.

The adjustable height feature saved me when I needed to fit tall containers on bottom shelves. And those little side hooks? Perfect for hanging my cleaning rags where they can air dry.

Only minor complaint - the wheels could be slightly larger for rolling over uneven garage floors. But they work fine on smooth surfaces.

After testing similar units, this one stands out for its combination of capacity (2100lbs!), mobility, and smart design touches like the side hooks. Worth every penny if you need serious storage that can move with your needs.
