I gave the review only 4 stars for one reason. The order processing and shipping time was great. The unit arrived in an appropriate box. But the fifth star comes off for one reason. The unit has had bolts on it, two to secure the collars to the forks and one that kept the pieces together in shipping that is replaced by the included knob. But the damn things were on so tight I had to use a 12-inch (or longer) wrench to get them loosened after I put the unit in a vice. They did seem to be a bit rusted in place. Otherwise, I am looking forward to using the unit with my bucket forks to move an oddly spaced pallet. NOTE: I find the syntax checker used here interesting and accurate.
