The short answer
ProtoArc and AZIO both sell keyboards and mice, but they are solving different problems. ProtoArc builds for comfort: split and wave-shaped keyboards, vertical and trackball mice, footrests and mesh chairs, mostly under $70. AZIO builds for looks and tinkering: typewriter-style Retro keyboards, colorful IZO boards, and hot-swappable Cascade kits you can re-switch without soldering.
- Pick ProtoArc if your wrists, forearms or shoulders are the reason you are shopping. It also has the stronger safety net: 30-day returns with original shipping refunded, a 2-year accessory warranty and free US shipping over $19.99. It is the stronger of the two brands in our reviews.
- Pick AZIO if you want a mechanical keyboard that feels and looks like a hobby object, or a $79.99 barebone to build your first custom board. Go in knowing the policies are tighter, which is the main reason it trails ProtoArc in our reviews.
- Spill-prone shared desk? AZIO's $39.99 KMC226 combo is IP67 sealed, which ProtoArc does not match.

Price levels: what your money buys
ProtoArc is the cheaper way into ergonomic gear. The EK02 Wave Keys keyboard costs $54.99 and runs up to 100 hours on a 500mAh battery. The EK04 split keyboard is $69.99 and ships with a separate numeric keypad you can park on either side. The EM04 thumb trackball is $26.99. For context, split keyboards and trackballs from the big ergonomic names often cost $80 to $130 and up, so ProtoArc lets you test a new posture without a big bet.
AZIO keyboards start higher because they are mechanical. The assembled Cascade 75% Wireless is $99.99 with a choice of four Gateron G Pro switches. The IZO Wireless with red switches is $129.99. The Retro Compact in Maple with a Japanese layout tops out at $229.99. AZIO also sells the parts: Cascade barebones at $79.99, Gateron switch packs at $9.99 and 110-key keycap sets around $39.99.
The cheapest real keyboard-and-mouse set at either store is AZIO's KMC226 at $39.99. ProtoArc's closest is the KM90-A Mac combo at $41.99, which adds backlighting but is Bluetooth only and does not work with Windows.
Ergonomics vs typing feel
This is the real dividing line.
ProtoArc's boards use low-profile scissor-switch keys, like a laptop. The point is posture: the EK04 splits the halves so your shoulders stay open, and the EK02's wave shape and memory foam palm rest keep wrists in a gentler angle. Two things to know from our product research: the EK04's palm rest is hard and cannot be removed, and split layouts take a week or two to get used to. If you want a softer start, the EK02 is easier to adapt to.
AZIO's boards are about the typing feel and the look. Hot-swap sockets on the Cascade line mean you can try linear, tactile and clicky switches in the same board. Red switches (as on the IZO) are light and quieter; blue switches are clicky and louder. None of AZIO's keyboards are split or tented, so if you are buying to fix wrist pain, AZIO is the wrong store.
Mice and the rest of the desk
ProtoArc's mouse range is its other strength. Vertical mice hold your hand in a handshake grip, and the EM04 trackball keeps your arm still entirely. Note that the EM04's forward and back buttons do not work on macOS, and some vertical models are sized for medium to large hands. ProtoArc also sells the parts of a full workstation: the Flexer mesh chair ($159.99, sized for roughly 5'1" to 6'0" and up to 220 lbs), a memory foam footrest ($33.99), a 31.5 x 15.8 inch leather desk mat ($19.99) and rollerblade-style casters ($34.99) that fit five of its own chairs.
AZIO sells the IZO Wireless Mouse ($49.99) to match its keyboards, but the rest of its catalog is keyboard hobby gear: keycaps, aluminum ESC keys, switches, a $9.99 switch puller and coiled cables.
Policies: where the gap is widest
ProtoArc's terms are among the clearer ones we have reviewed in computer accessories. You get 30 days from delivery, a full refund including the original shipping, and a prepaid label for defective or wrong items. Change-of-mind returns ship at your cost. Report damage or missing items within 7 days, and check your order fast, because orders usually enter fulfillment within 12 hours and cannot be changed after that. Hawaii, Alaska and APO addresses face restricted service.
AZIO's 30-day window counts from the purchase date, not delivery, so a slow shipment eats into it. Items must be new, unused and resealable with all packaging, or the return can be rejected or hit with a 25% restocking fee. Shipping and import taxes are not refunded, and you need an RMA number first. Delivery times and costs are not published. If you plan to try a keyboard and send it back if you do not like it, keep every bag and box intact.
Who should pick which
Choose ProtoArc if you:
- Have wrist, forearm or shoulder discomfort and want to try a split keyboard, vertical mouse or trackball for under $70
- Use a Mac and want a backlit, Mac-layout combo (KM90-A)
- Travel and want a folding keyboard (the XK03 is $44.99)
- Want a long warranty and phone support
Choose AZIO if you:
- Want a mechanical keyboard that doubles as desk decor
- Want to build a first custom keyboard from a $79.99 barebone
- Need a washable IP67 keyboard and mouse for a kitchen, shop or front desk
- Already own an AZIO board and want new keycaps
Consider both if you want ergonomic pointing from ProtoArc and a mechanical keyboard from AZIO. Nothing stops you mixing a ProtoArc trackball with a Cascade 75%.
