Perixx Periduo-505

Bottom line: The Perixx Periduo-505 ($49.99 on Amazon as of 2026-10-06): Split 3D-curved layout keeps wrists straight without learning a true two-piece board; main trade-off: membrane keys with short travel, not mechanical switches.

Manufacturer description

The Perixx Periduo-505 bundles an ergonomic split keyboard and a vertical mouse into one wired USB kit built around a single goal: keeping your wrists in a neutral position through a full workday. The keyboard uses a one-piece 3D-curved design that separates the keys into left- and right-hand groups, so your wrists stay straight instead of angling outward, and the integrated adjustable palm rest extender (repositioned with a movable magnet) supports your hands at the height that suits you.

SpecPicks Verdict

SpecPicks scored Perixx Periduo-505 using a rating × review-volume × price-fit model applied to published specs and reviews across the keyboards & mice category. Perixx's keyboards & mice lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Is the Perixx Periduo-505 keyboard mechanical or membrane?

Membrane. It uses short-travel tactical membrane keys under a curved, slim key-top geometry, so presses are quieter and shallower than a mechanical board.

Does the split keyboard come apart into two pieces?

No. It is a one-piece board that splits the key groups into left- and right-hand clusters internally, so you get the neutral wrist angle without positioning two separate halves.

What DPI does the vertical mouse run at?

The optical sensor switches between 1000 and 1600 DPI. It is a 6-button mouse counting the middle-click scroll wheel.

Will it work with my Mac or Linux machine?

Perixx lists support for Windows XP through Windows 10 only. It is plug and play USB with no drivers, but macOS and Linux are not claimed, so check the product listing before buying for those systems.

How big is the keyboard, and does it include a palm rest?

It measures 18.23 x 8.4 x 1.53 inches (463 x 227 x 39 mm) and weighs 1.5 lbs. An adjustable palm rest and a movable magnet for height adjustment are both in the box.
