I looked at these when I was initially buying things to jump start my hobby. My opinion of this type of workbench is that it was too small for most of the things I would want to use it for and for a fraction of the price I made a few saw horses and used some 3/4 plywood as a top until I built my work table.
I guess they have their place in a shop for some people, but to me they are quick and portable solutions for contractors to take 1+ to a job site and have little to no functional use in my shop and the projects I work on.
The last thing that steered me away was the price, for the same price you can build a pretty simple table setup that is larger and probably more stable.
Just my thoughts on it.
To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
