This is one really well-built, nicely designed and very, very useful hand truck that quickly converts to a 4-wheel flat cart. Assembling it took most of the second half of the day due to the limited instructions which essentially were “look at this picture of the truck and use it to figure out how to assemble it”. ;-/. There was a diagram showing all the parts, but what it lacked was “Step 1…Step 2…, etc. Or even an explanation that noted how to add and balance all the parts—basically you have to put all the parts together and somehow keep them from falling out of plumb before you can even put one screw in. Best advice, FactoryPure: offer one that comes pre-assembled!
