Great kit, easy to assemble (note: put swivel casters on opposite side of the tank shelf). Its great to have the ability to organize your welding gear.
Everything bolted up super easy! Hold both my Lincoln welders and the box has plenty of space for all the consumables. I lowered the bottle mount to fit smaller bottles. Everything is stout and sturdy. Honesty a great product
