Works well but no instructions
Works well, had to YouTube to see how they are correctly used. Would be good if instructions were enclosed. Used to see progress after knee replacement!

No instructions included.
A good gadget, but would be nice to have instructions on how to use it. Three sets of numbers around the dial and no idea what they all stand for.

Good value for money
As a non medical person I bought this item as I've recently had a total knee replacement. The only downside is I wish there had been some sort of instruction information with it but otherwise it does exactly what was needed

ACL Rehab Necessity
I purchased this product after my ACL surgery to ensure I was meeting my range of motion goals. It was easy to use and very accurate to what I was measuring at PT. This is a product you need if you are having a surgery or going through rehab to ensure your meeting your flexibility goals. Product held up well and is something I can use later or give to a friend who needs it. I would purchase again!
