Not sturdy. Wheels won’t roll and are buckling under weight and I only have one plant on it right now. Flimsy and racks won’t sit flat they are buckled. The plastic tore open after the first rain on the top and totally busted open after 2 rains. Had to remove it and throw it away even after covering it with a tarp. Can’t find a way to get a replacement cover either -( so I guess it’s just junk!
