Just what you'd expect, does it's job and does it well.
Very sturdy, requires some assembly but offers endless options to put it into exactly the position you want. flat, steep slope, front to back ,back to front etc.
Pretty wide so plenty of room to position your feet comfortably and very sturdy.
It's not cheap considering it's mostly plastic, but it is very strong plastic and I would rather buy this one again than one of the flimsy cheap ones that need replacing and offer less flexibility.
