Review on 440 LBS Capacity SOLEJAZZ Moving Furniture Dolly - Heavy Duty 4 Wheel Cart For Piano & Other Heavy Furniture, Blue, 1 Pack by Matthew Sytniak

I placed a small tree from my yard on this dolly after having my gardener dig it up, because it wasn't doing well in clay-like ground soil. I assumed it would be strong enough, as it's advertised to hold over 400 lbs. It wasn't.To my surprise, it bowed in the center, even though the large pot it held covered the entire dolly. I had to correct the distorted, concave shape with a heavy object placed on its underside, and let it re-form/re-shape itself during heavy heat and sun on my patio.Too late for a return/refund, my handyman attached three 2 x 4's to this object lengthwise (once it was reshaped back to normal) so that it can be weight bearing. I also disliked the fact that only 2 wheels pivoted/turned. It made it considerably more challenging to move, while sitting under my magnolia tree.My solution was buying two smaller dollies that attached, and had extra wheels to its center base when put together. These are better supporting my tree. I'm using the (wood-reinforced) Solejazz dolly underneath a smaller/lighter planter. This item was priced well, but failed to perform so it was money NOT well spent.
