The makers of the Zero Tension Mouse claim that their mouse does this job better than any other ergonomic mouse on the market, but this a bold claim. The truth is this mouse doesn’t do anything better for you than the Evoluent Vertical Mouse, or 3M Ergonomic Mouse does. The marketing of the product may be better and that’s why it is such a good seller. The Vertical Mouse by Evoluent and the Zero Tension Mouse are the two best selling ergonomic mouse input devices, but we think the Evoluent mouse is manufactured better, and will last longer. The Zero Tension Mouse has a high defective rate – which is a sign they are made with cheap materials and/or not put together very well.

The manufacturer’s website goes into really in-depth detail about how all of the muscles in the hands, arms and shoulders work when using a computer mouse. It is interesting information, but the real main function of this mouse is to simply put your hand and wrist in the “handshake”, or vertical, position to reduce muscle tension. Some people find this mouse to be amazing and some people just cant get used to it and go back to a standard mouse.

The makers of the Zero Tension Mouse say that the most important feature of the mouse is it’s ability to relax the shoulder and neck. Truthfully, this is the least important feature because almost nobody is going to rest the weight of their arm and shoulder on their computer mouse. This is something that has more to do with your worksurface, and what the position of your keyboard and mouse is relative to how you are seated. Arm and shoulder fatigue is much more easily controlled with an ergonomic keyboard tray for your desk, an ergonomic mouse is really to ease strain in your hand and wrist… you can’t expect it to go beyond that, or you will be disappointed. Nonetheless, a mouse like this may help hand and wrist strain for some people, unless of course you can’t stand using it after a week like most people.

We really don’t recommend this mouse and we believe a smarter decision would be the 3M Stick Mouse, or Evoluent Mouse.
