Bests & Worsts Reviews from Amazon

I ordered both the FG253100BLA (on the left in photos) and FG253104BLA to see if there was any difference. The 104BLA came pre-assembled; the 100BLA was shipped as three parts in a plastic bag. After following the illustration for assembly, I used each one for a while and found the following: The hinge on the 100BLA was stiff, not allowing the bin to drop all the way vertical when lifted, as the 104BLA did. The lip on the 100BLA had a slight curve into the bin, producing a gap with the floor when lowered, allowing dirt to be swept under the bin. The 104BLA's lip was curved slightly away from the bin. When lowered, the edge straightened out flat against the floor with the weight of the bin and handle on it. The 100BLA also had more mold flashing on the bin (seen in the close-up photo). The parts of each unit seem to be made with the same machines, but the difference is in quality control. They apparently pick the best parts off the line, assemble them, and check for smoothness of operation for the FG253104BLA. The rest of the parts get bagged and sold as the FG253100BLA.
