Contour RollerMouse Red Plus Thin Client — Centred Ergonomic Mouse
Rollerbar2800 DPIMemory foamLarger palm rest
The RollerMouse Red is the device that made the category, and Contour still describes it plainly: your mouse is why your shoulders hurt. It fixes that by putting a rollerbar directly in front of the keyboard — you push it to move the cursor and roll it to scroll, with either hand, so the arm never travels out to the side. The bar itself is larger and textured for tactile feedback, the body is recycled aluminium, and the wrist rest is memory foam rather than a plastic ledge. Underneath is an optical sensor at up to 2800 DPI in 10 steps from 600, with 6 buttons carrying 7 programmable shortcuts set in the Contour Personalization App. This part number is the wired version: USB-C plug with a USB-A adapter supplied, nothing to charge and nothing to pair. This is the Red Plus, with the larger palm support built for bigger hands. 425 x 157 x 24 mm (16.75 x 6.18 x 0.94 in), 1030 g (2.27 lb). Windows and macOS, 2-year warranty.
Compatibility — check before buying:
Start with the part number, because this one is specific. It is the Thin Client version of the RollerMouse Red Plus. Contour publishes no separate specification sheet for the Thin Client part number — everything quoted here is the published Red Plus specification, which the two share. What the Thin Client designation changes is not documented on Contour’s own pages, so we will not invent an explanation: if you are deploying into a thin-client, VDI or locked-down terminal estate, tell us the platform and we will confirm the behaviour with Contour before you order rather than guess. One thing worth planning for regardless: the 7 programmable shortcuts are set in the Contour Personalization App, and a locked-down terminal often cannot install it — the device still works with its default buttons, but budget for that if the shortcuts matter. Two more points. This is the wired version; Contour also builds a wireless Red under different part numbers, so check the code rather than the photograph. And the switch itself takes time — most people need a week or two before the rollerbar stops feeling deliberate, which is why Contour ships a 30-day money-back guarantee. Contour publishes no cable length for this model, so we quote none.
Best For
✓ Shoulder and neck pain traced to mouse use

✓ Larger hands that need more palm support
✓ Occupational-health and ergonomics-led procurement
✓ All-day pointer-heavy work
Key Features
A bar, not a mouse
Push the rollerbar to move, roll it to scroll. The pointer is in front of the keyboard, so the arm never reaches out to the side — which is the movement that costs the shoulder.
Textured for feedback
Contour makes the bar larger and textured specifically so you can feel where it is and how fast it is moving, without looking down at it.
Memory foam and recycled aluminium
A memory foam wrist rest rather than a moulded plastic ledge, on a recycled aluminium body — built to sit under the hands all day.
Seven shortcuts, either hand
Six buttons carrying seven programmable shortcuts in the Contour Personalization App, all within the centre line, usable left-handed or right-handed.

Frequently Asked Questions
Red or Red Plus?
Same rollerbar and same electronics. The Red Plus has a larger palm support built for bigger hands, which makes it deeper on the desk. This one is the Red Plus at 425 x 157 x 24 mm (16.75 x 6.18 x 0.94 in).
How long does it take to get used to?
Most people need one to two weeks before the rollerbar stops feeling deliberate. Contour ships a 30-day money-back guarantee for exactly that reason.
What does Thin Client mean here?
Contour publishes no separate specification for the Thin Client part number, so we will not guess. Tell us your thin-client or VDI platform and we will confirm the behaviour with Contour before you order.
Singular Expert Insight
Thirty years on, the Red is still the reference for centred pointing: everything since has been a refinement of this shape. If a vertical mouse only half solved your shoulder, this is the next step rather than another mouse. See our
keyboard accessories and our
wireless mice.
Buyer’s Guide
Buy it if
You want the original centred rollerbar, wired, with a memory foam rest and the larger palm support for bigger hands.
Skip it if
Your desk is too shallow for a centred device, or you need a wireless connection.
Also consider
The RollerMouse Pro if you want a slimmer current-generation body, or the standard Red for a smaller footprint.
