Prasacco 12 Inch Goniometer, Transparent Orthopedic Angle Ruler Plastic Goniometer 360 Degree Goniometer Angle Protractor Goniometer for Body Measuring Tape Goniometer Protractor Ruler

Works good. I used after knee surgery to measure bending progress

Product was very inexpensive and allows one to measure range of motion (ROM). Therapist saw it lying on the end table used it to measure ROM instead of pulling out his own gonimeter.

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!

Works well to measure knee flexing and extension

I recently had an ACL surgery and buying this has helped me keep track of my extension and flexion degree

I wanted one of these at home to monitor my flexion progress after total knee replacement. Def worth the small price.

I needed this device to measure my progress with my therapy. It was hard to figure out at first to read it, but once you figure it out it helps keeps you motivated

Excellent product.
