I own that, and trust me when I tell you that even when the legs aren't fully extended (as shown) the thing isn't super-stable.

It is impossible to get all four legs to exactly the same length (even if you use the guide marks). He has it resting against a wall for a reason.

I would recommend it, but it might wobble around a little if you put any weight unevenly on the surface.
