Below is a list of our frequently asked questions.

Every RollerMouse line of product is designed to relieve pain and maximize comfort while working. Its patented design eliminates harmful movements and allows users to continually use safer working habits and better posture. If you are looking to alleviate pain and strain, or just want to ensure that you can work comfortably all day, a RollerMouse is right for you!

Each RollerMouse shares the same ergonomic design principals that make it the premier solution to combat the negative effects of using a computer mouse. That said each RollerMouse is designed for a different type of user.

RollerMouse Pro3- Our only model long enough to accommodate a full sized (18 in.) keyboard and provide full support for the 9-digit number pad

RollerMouse Free3- Great for desktops and compact keyboards. Free3 also comes with the most customizable buttons for those who prefer to use shortcuts instead of drop-down menus.

RollerMouse Red/Red+ – Our most advanced and versatile mouse. The Red is a great companion for keyboard trays and desktops alike. The Red+ gives users an extra 2.25 inches of palm support to fully support those with large and extra-large hands. On top of that, it is our most precise RollerMouse ever, allowing users unparalleled control of the cursor.

Yes. RollerMouse products are designed to operate on a plug-and-play basis on a PC or Mac. The RollerMouse Free 3, Pro 3, and Red all have a PC mode and Mac mode for shortcut button compatibility. Please see our online product manuals here for help on switching between PC and Mac mode.

RollerMouse will work on Linux devices, but we do not provide technical support for this software.

If you’re using a Mac with RollerMouse Pro2 or Free2, the ‘one touch’ copy and paste button functions will not work without a driver unless you are using ‘Microsoft Office for Mac’.

All of our RollerMouse products will work with any flat edge keyboard, however, we do not recommend using a RollerMouse with a curved keyboard, or a keyboard with a built-in wrist rest.

Our Balance Keyboard is designed to be fully compatible with the RollerMouse Red, Red Plus and Free product lines.

The RollerMouse Pro product line is best suited for workstations that include full-sized keyboards.

Yes, RollerMouse can work in conjunction with other mice, both external and integrated (e.g., touch pads).

Tip: If you decide to keep your traditional mouse when learning to use a RollerMouse, make sure to place your traditional mouse out of reach, so you don’t reach for it out of habit.

All RollerMouse products are pre-programmed with smart button functions. This built-in software gives users the most ergonomically beneficial set of button functions so you can just plug-and-play.

However, you may wish to use the driver to manually change button functions for even greater functionality and variation.

Due to the difference in copy and paste commands on a Mac, the corresponding buttons on Pro2 and Free2 won’t work without the driver. RollerMouse Free3, Pro3, and Red models all have a PC mode and Mac mode built in. Please see our online product manuals here for help on switching between PC and Mac mode.

As of this time none of our RollerMouse products are meant to be compatible with KVM switches. Due to the nature of some KVM switches, you may find that your RollerMouse is in fact compatible; however, the RollerMouse is not designed to be used with a KVM switch.

Most KVM switches must determine if the input device is a keyboard or mouse, which creates a problem when connecting a RollerMouse. Despite this, there may be some KVM switches that are able to recognize devices other than a standard mouse or keyboard.

Yes, all wireless products from Contour Design are secured by encryption.

The communication between the dongle and the wireless product (2.4GHz) is secured by an algorithm called AES 128 bit, which is an industry standard when it comes to encryption on consumer devices.

During the pairing process a random encryption key is generated and exchanged between the dongle and the wireless device, and that is stored and used afterwards to secure the communication.

The pairing process is kept secure by the fact that it happens only upon user request, and it is intentionally very short range which prevents eavesdropping.
