There are primarily three questions concerning the Evoluent that I regularly come across.
The first one is, “How do you say Evoluent?” Start off like you are saying evolution, but you stop at “evolu” and add an “ent” on the end, similar to the word “fluent”.
The second question is, “Don’t you feel the bottom of your hand dragging on the mouse pad?” This depends on the shape and size of your hand. I have a pretty thick hand and feel it touching the mouse pad at times, but it has never bothered me in the slightest. I’ve used the mouse both at work and home for almost two years, so consider it well tested. There is also a small lip at the bottom of the mouse that allows your pinky to rest on it, so you are not rubbing your pinky on the mouse pad.
The third question is rarer and I typically hear it from gamers (I do highly recommend this ergonomic mouse for gaming). I have been asked whether or not you can grip it well when you are moving the mouse quickly back and forth in multiple directions. Even in a frantic gaming situation, I have never had to apply much pressure to control the mouse; your hand can stay relaxed. You actually need to apply less pressure to this mouse then a regular mouse due to the contours of the mouse design and the position of your hand.
On the bottom of the mouse, there is a button that will allow you to change the DPI of the mouse on the fly. DPI means dots per inch: this basically means the number of steps the mouse will report when moved an inch. It is used to change the relation of space that the mouse is moved to the space that the pointer on the monitor is moved. The higher the DPI is, the less you have to actually move the mouse. Accuracy at a high DPI has to be learned; however, it is a useful feature because you do not have to physically move the mouse as far. Although most computers offer a control for a mouse’s DPI to be adjusted, it is convenient to have the adjustment available directly on the mouse.
There are three current models to choose from: Wired Right-Hand, Wireless Right-Hand, and Wired Left-Hand. Unfortunately, the left handed model is a previous version and is slightly different from the right handed versions. It does not have a lip on the bottom of the mouse and along with the wireless version, it does not offer a DPI switch.
Overall, you cannot beat the Evoluent Vertical Mouse. I personally have never had any problems using a regular mouse, and I didn’t even realize that using one aggravated my forearm. But after using the Evoluent, I don’t want to go back.
