Digital Cameras Photo Reviews of KeyOvation VM2-LSB Vertical Mouse - Optical - USB - Silver, BlackCustomer Review: Good hand positioning, but mouse buttons too stiff Summary: 3 Stars
I've been using this mouse for a few weeks now. I purchased it after receiving several recommendations from peers who've had RSI issues. I'm right-handed, but have been alternating mousing for a few years now, so switching from right-to-left was an easy adjustment for me. Although I've been regularly using my left hand for mousing, I had previously kept the buttons configured for a right hand. That's been the biggest adjustment for me, but to be fair, I felt that I should adjust to the default layout since this mouse is strictly left-handed. So far, so good.
It's comfortable for my 7-3/4" medium-to-large hand. At first, I thought my pinky finger was getting sore from the positioning (i.e. other fingers resting on it), but that was for only a day. With some positioning adjustments, my shoulder, arm, wrist, and hand all seem to be much more comfortable than with traditional mice.
The accuracy is decent. Good DPI as noted in the item description.
I'm glad the thumb button is "dead" by default as I keep clicking it on accident.
There is a difference in precision clicking since the mouse buttons are pressed on the horizontal axis instead of the vertical one, as others have noted. But I'm adapting without even trying -- like most new things, it just takes using it to get better.
The height of the mouse is also something to get used to, if only not to keep knocking it off of my KB/mouse tray. That's just me being clumsy I think.
My only meaningful complaint is that the mouse buttons require more force to click than I expected. They feel almost as stiff as the right-handed Logitech mouse I had been using (MX518) or the MS Wheel Mouse Optical. I was hoping for something like the HP WX414AA Wireless that I had picked up as a temporary replacement for the painful (to me) MX518. After a day of mousing, I would describe my left hand fingers as being "tired". As I've only been using this mouse a few weeks, I suppose that could be residual discomfort from previous mice, but as it's my left hand, there's not nearly as many mouse miles on them as on my right.
Overall, I'm glad I purchased this mouse. It's more comfortable for my hand than "horizontal" mice. But the buttons need to be softer.
