Review (4/5): Easy to use dynamometer
This is a quick way to check an adult or older child grip strength. I like the marker to assist with the readings. The only drawback is that it did not include and information on use, or have a table of average grip strength ranges. I could not find this information available from the manufacturer's website. I did find a study by a competitor which gave me averages though. Small enough to carry around in my therapy bag though.
