Jamar Smart Hand Dynamometer, Digital Lightweight Max Force Indicator to Measure Hand & Grip Strength, Cordless Device with Wireless Connection to Mobile App, Easy Squeeze Adjustable Evaluation Tool

Having used both manual and digital Jamar grip Dynamometers, I can say there's no difference to the weight, feel and size.I bought this one as a gift to my attending/ chairman on completing my residency.Pros: Easy button operation, large screen is easy to read (not back-lit). It has the same heavy feel as the manual model, which you want for grip strength durability. Worked very well right out of the box. Nice black plastic carrying case with handle, interior foam insert.Fancy digital features include saved measurements, averaging, variances etc.A digital grip/ pinch set can easily reach 700-900$, so this was quite the value.Cons: priceIn general, digital will be on the order of double the manual price. Manual works just as well just usually requires reading a small-interval dial. I will rarely if ever use averaging, coefficients, or other digital features. I guess this is useful for serial measurement comparisons.Overall: Very well priced digital grip dynamometer with carrying case, some advanced digital calculation features. Consider a less flashy manual dial model for greatly reduced price.

I'm used the the old fashioned dial Dynamometer, but decided to try the digital when purchasing it for my business. It took a bit of getting used to, but now I/m very happy with it. I find it quicker to get the number than looking at the dial.

Light weight, accurate and suitable for children

At a clinic where we use this every day for patient evaluations, it stopped working after 3 months and consistently read a 243 lbs measurement, regardless of how hard or how gently it was tested. Called the company and they would not replace it or recalibrate it unless we paid another $140.00. For a product that expensive and having failed in 3 months, it was a complete waste of money. Very disappointed.

Apparently, in an attempt to make this lighter in weight, the manufacturer changed from a durable metal casting (used in the standard Jamar) to aluminum and plastic. The moveable handle is easily damaged. I dropped mine while changing positions, from a height of about 3 feet, and the handle bent so that it would no longer snap in place. I managed to bend it back using a vise and pliers so that I could use it again, but in a clinical setting this would be a real problem if it occurred during testing. I noticed that another user reported that this handle broke on their dynamometer.I contacted the manufacturer to see if replacement handles were available and was told that NO, they are not. Anyone who has used a hand dynamometer for any period of time realizes that accidentally dropping the handle while changing positions is a common occurrence. You could render your device unusable and irreparable very easily!!! I do not recommend this device for serious clinical use.

Meets my needs in an Orthopedic office, clinically, and for IMEs

Solid!

Although the outline of the product and the instructions indicate the digital dynamometer completes rapid exchange testing, it does not. Rapid Exchange (or REG as it is known) requires alternating (exchanging the dynamometer) from one hand to the other and this device does not allow this type of testing. This is disappointing specifically since Jamar is the hand grip that was utilized in the research that developed the norms that are utilized for hand grip testing.
