Does anyone have any experience of a 'vertical mouse'? [closed]

"I use an Evoulent VerticalMouse 3 at home and work; it's done wonders for my wrist pain. A quick list of pros and cons that I've noticed:

The Good

The grip is far more comfortable than
on traditional mice
The sensor, despite
being infrared, goes up to 2400dpi (I play a lot of video games, so this was key)
The build quality is
solid (except for one button…)

The Bad

The mouse is fairly light, so if you prefer some heft to your pointing devices (like I do), using the VerticalMouse takes some adjustment
You need to have good arm/elbow support
Thumb button feels cheap
The DPI switch is on the bottom of the mouse

Like Ivo noted, the best thing to do is to give them a shot!"

"Although it may not be completely in line with your question. If you want to beat RSI you should start mousing with your other arm every now and then. I can tell you that certainly helps and is easy.

Next to this I have a trackball, the one you see below and I still use it alot. It is so nice when you get used to it. Lately I also noticed that it is quite usefull in situations where you dont have much space to mouse (trains, schools, other peoples desks when you bring your laptop.. ).

But on the vertical mouse, I have never used it but as said above, you adopt every input devicde quite fast :D."

"I have been using a DXT Vertical Mouse for some time now. Its designed to be used with your finger tips rather like holding a pen. Here are some pros and cons.

Pros

It has definately helped to make my mouse arm more comfortable as the position is much more natural.

Very nice to use, responsive and accurate.

Well designed and well made

Its about the same size as a normal mouse so looks good on the desk.

Can be set up to use left or right handed simply by pressing a button on the mouse. I find this particularly useful as I now can have two mice. I use the DXT with my left hand and a normal mouse with my right, switching regularly between them to reduce the load on any one arm.

Cons

Its taller than a normal mouse so I do have the tendency to knock it over when quickly moving my hand from the mouse to the keyboard. However with practise this is happening less often.

A bit pricey

To start with clicking the secondary mouse button didnt feel at all natural, took me a while to get used to it.

Overall I wouldnt say this totally solved my problems but it has definately helped."

"At work I’ve used the Aerobic Mouse for years and find it very comfortable. It cradles your hand, oriented on edge, and allows your hand to completely relax except to click or scroll. Mousing accuracy is reduced because movement comes only from your arm and wrist, not fingers. Your elbow and forearm need good support.
The included software provides automatic clicking by hovering and other aids for the physically impaired. I only tried it briefly, years ago, and do not remember it now. The cost of the mouse [~100 USD] must be for the software because the mouse itself is cheaply made.

At home, I emulated this design with a Logitech 'Trackman Wheel' [~30 USD] modified by gluing a 40 degree wedge under the left side to roll the trackball housing to the right, so that the ball faces up. This assembly is fixed to the keyboard tray of my desk to keep it positioned comfortably, my hand resting on edge, thumb up. These devices have relieved my wrist pain and numbness.
