Everything but the sticker.
Sticker came stained and creased. Everything else was good.

Great way to test flexibility for a business like mine
We bought this to use in fitness challenges when our monthly goal is to increase flexibility. Easy way to measure it - the sit and reach test! All of our members found it easy to use. It was also easy to put together.

Good quality S & R for price, easy setup
This is the cheapest one of these I could find for my class, and it serves its purpose perfectly. My only issues are that the screws for the slide come loose after continued use (like if I'm testing all my classes one day) so I will have to keep an eye on it and tighten it, otherwise everyone in class is searching for a bolt and spring that popped off the bottom.

works fine
I was worried about whether to order it or not from reading other reviews but this thing assembled just fine. No problems.

I drilled them myself and the box works fine other than the extra holes
I ordered two of these. There are some words that aren't spelled correctly. Also, the holes on the top of one of the boxes that you have to assemble were incorrectly located. I drilled them myself and the box works fine other than the extra holes. This thing isn't made in the USA that's for sure.

Functional
We use this classic sit-and-reach in my gym Maxwell’s Fitness Programs. It’s great.
