See the bundle BundleThe RollerMouse Red Plus sits in front of your keyboard, not beside it. No reach. No shoulder load. No buildup.
A flat computer mouse sits six to ten inches off-center. Every reach is a small movement. Multiplied by 10,000 a day, it stops being small.
Every reach across your desk fires the same upper-trapezius and deltoid bundle. By 2 PM that muscle is locked. By 5 PM you're carrying it home.


You switched to ergonomic vertical mouse. You stood more. You stretched more. But the moment your hand moved back to the side of the keyboard, the cycle started again. Because the problem wasn't your posture. It was the reach to your mouse.

RollerMouse solved their wrist and shoulder pain.
Qvadrant survey · Commissioned by Contour Design
No grip. No reach. No twist. Your hands stay where typing already puts them.

The Rollerbar sits in front of the spacebar, where your hands already are. No reach to the side. Both hands stay over the keyboard.
A traditional mouse keeps your hand clenched all day. The Rollerbar replaces that grip with a relaxed fingertip rolling a bar.
EMG research measured 79% less shoulder muscle activity during rollerbar use versus a conventional computer mouse. *

Ambidextrous by design. Pass the work between hands during a long day. Your dominant side stops being the only side that pays.
Peer-reviewed evidence
Three peer-reviewed EMG studies tested the RollerMouse against a conventional mouse. Different institutions, different methods, same direction.

I’ve been using this company’s RollerMouse product for at least 15 years. As a result, it eliminated all the pain in my forearm and wrist caused by a traditional mouse.

Verified buyers
Three verified Judge.me reviews. Three different starting points. Same outcome.
“No more PAIN dragging my inflamed ulnar nerve around the table, no more mouse arm pain, no more shoulder and back pain. Now I work quickly and comfortably in my comfort zone.”
“I’ve suffered finger, elbow, wrist and shoulder pain for the last 10 years at least. One week of using the Re:d and all the pain is GONE. Everything else is meaningless against that fact.”
“Pain and lack of productivity are expensive. Doctor visits are expensive. Physical therapy and surgery are expensive. If you’re at the point of considering those, try this first.”
