ProtoArc Back to School Sale: Every Deal Worth Taking

The EM01 NL is the product most people should try first if a standard mouse leaves their wrist sore by mid-afternoon. Because the ball does the moving, your forearm stays planted, and the sculpted rest supports the hand rather than forcing it flat.

• Trackball design keeps the wrist and forearm still
• Multi-device pairing over Bluetooth and 2.4G
• Rechargeable battery lasts weeks per charge
• Takes a few days to retrain muscle memory

Split keyboards fix the two habits that cause most typing discomfort: hunched shoulders and bent wrists. The XK01 separates the halves so you can set your own shoulder width, and the contoured key wells keep the wrists neutral.

• Split halves adjust to your natural shoulder width
• Contoured layout with integrated palm support
• Works with Windows, macOS, iPadOS and Android
• One to two week learning curve

A vertical mouse is the easiest ergonomic switch to make because it still moves like a normal mouse. The EM11 NL holds the hand upright, which removes the forearm rotation that a flat mouse forces all day.

• Handshake grip removes forearm twist
• Familiar pointing motion, almost no learning curve
• Quiet clicks suited to shared offices
• Less wrist relief than a trackball

The EK01 is a travel tool rather than a daily driver. Folded it fits in a jacket pocket, opened it gives near full-size key spacing with a touchpad, which is enough to answer email or draft a document from a tablet.

• Folds to pocket size for travel
• Built-in touchpad on supported models
• Pairs with iOS, Android, Windows and macOS
• Fold seam sits under the typing area
