Review: 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.
Review: 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.
