The Evoluent vertical mouse (or a previous generation of it) is one of the very few ergonomic mice that I’ve actually used, day-to-day, for more than a week or so. Unfortunately, that period of “more than a week” was before my previous review, and thus is currently about six years in the past. During that time, I recall the previous-generation Evoluent being quite handy and nice to use, largely due to its well-designed and stable driver (on which more in a moment). Compatibility Microsoft Windows® 7 or later• Includes driver for Windows 7, 8, 10 and 11 for configuring the buttons. The driver is optional but highly recommended. VerticalMouse still has basic functionality without the driver. USB only; not compatible with PS2 adapters. May be compatible with some USB KVM switches but it is not guaranteed. Press and hold the – end of the pointer speed button and plug in the USB connector. If your mouse is a later production unit, the logo will turn off. To turn on the logo again, press and hold the + end of the pointer speed button when you plug in the USB connector. Windows enables the mouse to wake the computer from sleep by moving it. The setting is in Control Panel, Device Manager, Mice and other pointing devices, Evoluent VerticalMouse, Power Management.

Press the pointer speed button on the mouse to set the hardware pointer speed to the MD (medium) setting. Evoluent Mouse Manager for VerticalMouse 4 and D Wired and USB wireless versions of the VerticalMouse 4 require no pairing. They are plug and play.The driver may be installed after they are plugged in. The mouse is probably on a reflective surface. Put it on a completely non-reflective surface, such as a cotton mouse pad. Q: What should I do if the pointer seems sluggish or moves randomly in response to mouse movement?

Press the Pointer Speed button on the side of the mouse to light up two to three indicator lights for optimal pointer speed. The downside to a vertical mouse can be its degree of accuracy. The shape moves your hand higher up the body and further away from the mouse sensor, changing the correlation between how you move your hand and the path of the cursor. Even after spending weeks with a vertical mouse, it can take an extra adjustment to line up the pointer with a small icon. That may go away over time, but it's a significant change that you should be ready for if you want to go down this road. Earlier models have an illuminated logo that cannot be turned off. Later models may be turned off this way: Based on alkaline battery with typical office use. The battery may last longer with less use or shorter with more intensive use. Compatibility: Lights on top of the mouse that indicate the selected pointer speed from among four levels. They stay illuminated on the wired models, and are momentary on the wireless models. Optical Wheel:

The lights blink rapidly when the battery is low. Replace the battery. Resetting Wireless Receiver Or Pairing New Receiver Wired and wireless USB models are compatible with Mac computers as well as Windows, Linux and Unix computers. The patented shape supports your hand in a fully upright handshake position that eliminates forearm twisting. Many users said earlier models relieved their hand, wrist, or arm painEvoluent D benefits from all the great features of its predecessors, with a few added design flares to keep your mouse hand better-supported and comfier than ever. True to form, Evoluent D is a vertical mouse that encourages your hand and forearm into a neutral handshake position to avoid unhealthy twisting. Not only does this position feel natural and effortless, it also reduces your risk of aches, pains and injuries so you can be productive at your computer for longer. Apple Mac® OS X 10.5 to 10.14• Includes Mac driver for configuring the buttons. The driver is optional but highly recommended. VerticalMouse still has basic functionality without the driver. Some functions of the Windows driver are not available in the Mac driver. Wireless USB receiver requires a full-size USB port. Computers with only USB C ports require an adapter (not included). Bluetooth does not require a USB port. Programmability: If pointer movement is unreliable, use an extension cable to position the receiver farther away from other USB plugs or devices. If you often unintentionally press a button, you may disable the button. Please install the driver and select the Disabled function for the button.
