I opened it and put it together in about 8 minutes! Everything works and the lifting positions are good! Assembling the parts took maybe 5 minutes. Unfold, cut a few zip ties at the center, screw the legs on, gold it back and flip it into the legs, then plug it in! ❤️ 
The caveat the box is deceiving. Its bulky because it has nothing to hold it by. Im too short to carry it up a set of stairs alone, and wanted to surprise hubby, I took it out of the box outside. The whole thing was in 1 piece  of plastic. It was manageable alone using the plastic bag to protect it from the ground in the plastic (~60ish lbs).
