Query: OK, but the handle is too short for stairs.

Not all that robust. It doesn't seem capable of handling the weigh suggested on TV, but otherwise OK. The one problem I did encounter is that the handle is too short for going up and down stairs. I'm only 5'8" tall and had to bend over to pull it up the stairs. My wife is shorter than me and also found the handle too short for average stairs.
