Goniometer
If you have had knee replacement surgery this is a great tool to check range of motion.

Purchased for my massage studio. Sturdy. Works great.

Works just fine
This "goniometer" (who came up with that name?) works perfect. It has the right amount of friction to hold its position after taking a measurement. Probably not as durable as the one my physical therapist uses, but for $6 I'm completely satisfied.My only concern is the rivet doesn't appear to be all that securely riveted over, but so far it's shown no sign of pulling out.

Good quality product
Good to have when you want to measure your own progress versus have a therapist do it. I didn't necessarily use it very often though.

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!
User
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
User
Perfect
