Great Mouse...for a while, Helps with RSI, but has technical issues and is not very durable
By Paul C. Easton
I purchased this expensive mouse to help with RSI. Other than having to uninstall prior mouse drivers, setting up the mouse was fairly simple. The physical design was nice and was much more comfortable than using a horizontal mouse. Also, as a lefty, I appreciated having a convenient, programmable five-button layout. Mouse performance was good and pointing was precise, although I am not a gamer.After using it less than a month, however, "button one" stopped working. This is the "pointer/index finger" button that is the default button for primary clicks ("left clicks"). In the middle of working one day, after having made no changes to the system, I could no longer perform primary clicks. I rebooted the computer and when I first move the mouse after windows loaded, it drew a blue selection rectangle, even though no buttons had been clicked.Using keyboard shortcuts, I brought up the Evoluent Mouse Manager software and remapped the primary clicks to button two (the middle-finger botton). This made it usable again, but much less useful and not as comfortable to use.I visited Evoluent's sparse support site and based on the information there, I un-installed the driver, reinstalled (trying both the CD and downloading from the website) it had the same issue. I had not moved the mouse from the first port I plugged it in, but based on the support site, I uninstalled the driver again, plugged it into another USB port and reinstalled the driver. Same problem. When I first used the mouse after rebooting or unplugging and replugging in the mouse, it draws a blue selection rectangle until I hit the middle button (now remapped to function as the left click). Button one does nothing, no matter what I map it to.I tried plugging it into a Mac and it was recognized and I could move the cursor and right click and button two worked as a double click (its default behavior), but the button one does nothing. Also, like in windows, when I first plug the mouse into the computer, and move it, it draws a blue selection rectangle.The reseller I purchased it from (BugsEyeDigital through Amazon) only allows returns within 14 days. But Evoluent's support did respond to my e-mailed support request and offered to check it for defects. If a defect is confirmed they will send me a new one, if not, they will send it back to me. The problem is that I am overseas and for the cost of shipping, I'd be better off buying a new mouse.Strangely enough, the primary button eventually began working again. I was just using the mouse when I accidentally pressed the upper button close by the scroll wheel and it worked. Pressing in the center or top of the botton did nothing, but when I pressed right at the corner near the scroll wheel, it was working. I thought I must be pressing the middle button at the same time, but I tested and ensured that I wasn't. After using the primary button a number of times by clicking in that sweet spot, it eventually began to work, no matter where I pressed down on the mouse. Now it is working normally and I've remapped the buttons to my preferences.I'm still not sure what happened. Could a piece of something have lodged itself under the primary click? I could see how that would be more likely to happen with a vertical mouse than a horizontal mouse. In any event it has been working fine now for months, so I've changed my rating from two to four stars. I love the form factor and like how programmable this mouse is. Switching to a handshake-grip mouse has helped reduce RSI discomfort.It would get five stars if the company had better support and if it were wireless.UPDATE: after about 1 and a half years of using this mouse, I'm ready to buy a new one. A little after a year's worth of use, the matte coating started to wear and peel off. Ugly, but didn't really affect its use. Starting about a weak ago, however, after having used the mouse for just under 1.5 years, the primary click button is acting up again. A single click often is registered as a double click. As much as I like to form factor, this mouse really isn't built to last. I'm a heavy user, but mostly for general office use. I use the mouse many hours a day most days of the year, but not for gaming or any particularly punishing to the mouse buttons. Considering the cost, I was expecting something more durable.I'm am now looking for a replacement, I'll consider the same mouse or a similar one from the same manufacturer, but I am certainly looking for more durable alternatives. I've knocked my rating down to three stars.
