There were some complaints about the short handle. This model has a lock on the handle rod that allows it to telescope to different lengths. See video.
Also, it was posted that all four wheels moved from side to side on this model but it appears that with this one the back wheels are locked and the front ones move. See video.
Storage: several others have commented that the only way to store this is resting on its side. Because of the way that the wheels work now, I am able to adjust the front wheels to get it to stay up against the wall. See the picture attached.
Quick test in the garage and it seems to be working pretty well. I'll try to update this with future usage.
