Adesso - iMouse Wired Optical Ergonomic Mouse - Glossy black

While I do not suffer from RSI or carpal tunnel syndrome, the shape of this mouse effectively relieved the shoulder & neck pain I was experiencing from long-term computer use. Combined with good posture, the vertical orientation can prevent the shoulder from rolling forward and inward. It also feels like a more natural wrist position. The relationship between the mouse pointer on screen and where I'd expect it to be based on my hand & finger position took a couple weeks to get used to, as did the difference in clicking. Unlike a normal mouse where you press your finger down toward the desktop, with this mouse, it's more of a pinching movement toward your thumb. For the first month or so of use, this caused enough wiggle to interfere with double-clicks registering properly, but I've learned to adapt. I think for me, a mouse that's at less of an extreme angle would be better without compromising the superior posture. Functionally, it's pretty basic, with standard left & right buttons, 2 thumb buttons (forward & back website navigation), and a clickable scroll wheel. The DPI switch is responsive, but I'm not a fan of either of the 2 settings it uses, and they can't be changed. I'm also not a fan of the aesthetics or feel of the glossy black finish, but the blue LED swoop on the side, while unnecessary, is a nice touch. The cable is a little bit too stiff, and coupled with the tall height and light weight, this mouse is quite easy to knock around unintentionally. I would suggest trying this if you are looking for a more ergonomic solution for general home or office use, but be aware there may be a learning curve due to the nature of this shape. I would not recommend it for gaming or other tasks requiring higher precision & speed. Aside from the vertical orientation, this is a fairly basic mouse that is showing signs of wear (squeaky wheel) after only a month and a half of use, but for its price, it's not hard to overlook some minor faults.

I can’t use any form of wireless mice at work (DoD). I also am not allowed to load any drivers. Any peripherals I purchase have to be “plug and play” with Windows 7/10. We use either HP or Dell stock mice and keyboards w/ built in CaC readers. I am comparing this mouse Adesso Vertical USB mouse to the medium Evoluent VM4 Vertical USB mouse. Adesso: Pros: All the features seem to work on this mouse without any additional drivers. Two buttons on the right and scroll wheel work just like stock mice. I cannot program change the function of the third button which is too low and my ring finger already has nerve damage (right click) without installing drivers. Cons: So far only see one size and it’s a smaller size. I have a large hands so I wish it came in a medium or was a little bigger. The bottom of my hand/palm is already sore from years of using government issue stock mice. The bottom of my hand rubs the desk while I use this mouse. So for the price and compatibility with true “plug and play” abilities .... it is a great deal. Also everyone thinks it looks cool the subtle accent blue light on the left side is the shape of horizontal arch .... get a lot of comments “cool mouse”, “looks like something from the StarTrek”, etc.!

I like the mouse because it definitely gives the hand a break from the usual position. The only thing I take a little issue with is that sometimes I feel like I need to lift it to get it to track better. They should consider making one for lefties.
