Azeron Cyborg II vs Razer Tartarus Pro: which should you buy?

Both replace your keyboard hand with a dense set of mappable inputs. One is 3D printed to your exact hand with a true analog thumbstick; the other is a fixed, familiar keypad grid at under half the price.

The short answer

Get the Azeron Cyborg II if you want a layout custom-fit to your hand with real analog thumbstick movement, and you're willing to spend real hours relearning where your fingers go. Get the Razer Tartarus Pro if you want a conventional keypad grid you can map in minutes, at under half the price. Neither is the better keypad in the abstract; the Cyborg II asks for a real adoption cost the Tartarus Pro doesn't.

This isn't a spec-for-spec comparison. It's a decision about how much adaptation time you're willing to trade for a keypad shaped around your exact hand instead of a fixed grid.

Best for a custom fit

Azeron Cyborg II

Best for: a player who wants a layout 3D printed to their exact hand, with a true analog thumbstick for movement.

Tradeoff: a real learning curve GamesRadar's review flagged even after extensive hands-on use, a higher price, and build quality the same review called still a little fragile.

Best for a fast, familiar setup

Razer Tartarus Pro

Best for: a player who wants a conventional keypad they can map and start using the same day, at a fraction of the Cyborg II's price.

Tradeoff: a fixed grid with an 8-way analog thumbpad instead of a true thumbstick, and no custom fit to your specific hand.

Amazon availability, color, and configuration can change. The Cyborg II ships as a custom 3D-printed order; confirm your hand measurements and lead time on Azeron's own listing before buying.

Custom adjustability only pays off if you accept the relearning cost.

One is shaped to your hand, the other to a generic grid

The Cyborg II arrives 3D printed and adjustable with an included Allen key, so tower height, spacing, and angle can be tuned to your actual fingers. GamesRadar's review specifically credited the "Hall Sensor thumbstick" and "much more refined" top towers as improvements over the original Cyborg. The Tartarus Pro doesn't adjust to your hand at all beyond a 2-position wrist rest; it's the same fixed grid for every buyer.

A true thumbstick changes what movement feels like

Azeron's Hall Effect thumbstick supports genuine 360-degree analog movement or WASD emulation depending on the game, which is a meaningfully different input than Razer's 8-way analog-optical thumbpad. The Tartarus Pro's dual-step actuation still gives per-key analog behavior, but it's discrete directions, not a free-moving stick.

The learning curve is not marketing language, it's a documented cost

Azeron's own onboarding material estimates roughly 10 to 20 hours before the Cyborg II's layout feels natural, and GamesRadar's review, written by someone clearly enthusiastic about the device, still listed "learning curve" as a con and noted it "may not be the most intuitive for sidescrolling or fighting games." A Tartarus Pro buyer coming straight from WASD adapts to a fixed keypad grid considerably faster, which matters for anyone rebuilding an OSRS keybind layout under a deadline rather than over a few weeks.

Build quality and price track the same tradeoff

GamesRadar's review noted the Cyborg II's "build quality can still feel fragile" despite the design refinements, on a product priced well above the Tartarus Pro's roughly $130 tier. The Tartarus Pro is a mass-produced Razer product at scale, reflected in its far larger Amazon review count and lower price.

How much physical adjustment will you use?

Rebuilding a long-term MMO layout from scratch

Azeron Cyborg II

Worth the relearning period if you're willing to invest in a layout custom-fit to your hand for years of play, not just a single season.

Wanting true analog movement under the thumb

Azeron Cyborg II

The Hall Effect thumbstick is a genuinely different input than a directional pad, useful for games that read analog movement.

Preserving existing keypad muscle memory

Razer Tartarus Pro

A fixed, familiar grid lets an existing keypad user remap binds in minutes instead of relearning finger positions.

A tighter budget for a first macro keypad

Razer Tartarus Pro

At roughly half the Cyborg II's price with a far larger review base, it's the lower-risk way to try a dedicated keypad for the first time.

What neither one fixes

Neither keypad creates a good keybind layout by itself; both are only as useful as the binds you deliberately assign to them, and a cluttered or inconsistent layout stays cluttered on either device. Analog movement on both depends on the game actually reading analog input correctly, so results vary by title and neither guarantees smoother movement everywhere. You still need a mouse in your other hand either way; neither device replaces mouse-based aiming, camera control, or clicking.

Questions people ask about the Cyborg II vs Tartarus Pro

Is the Azeron Cyborg II good for World of Warcraft keybinds?

Yes, and it's one of the use cases Azeron markets it for. Its 30 mappable inputs and analog thumbstick can hold a full rotation of binds under one hand, but expect a real adjustment period, since GamesRadar's review specifically listed a learning curve as a downside even for an experienced reviewer.

Does the Cyborg II replace a keyboard or a mouse?

It replaces the keyboard hand only. You still use a mouse in your other hand exactly as you would with a normal keyboard-and-mouse setup; the Cyborg II's 30 inputs and thumbstick take over everything your left hand used to do on WASD and nearby keys.

How long does it take to learn a Cyborg II after using a Tartarus?

Azeron's own onboarding guidance puts real adaptation at roughly 10 to 20 hours, since your fingers are learning a 3D-printed layout unlike any keyboard. A Tartarus Pro, being a fixed keypad grid closer to a normal keyboard corner, has a shorter adjustment period for players coming straight from WASD.

Is the Tartarus Pro still sold new in the United States?

Yes. It's an Amazon's Choice listing sold directly by Amazon.com at the time of writing, in both Classic Black and Mercury White. Availability and configuration can still change, so confirm the exact listing before buying.

Can either keypad use analog movement in every PC game?

No, both depend on the game reading analog input correctly. Azeron's Hall Effect thumbstick supports 360-degree analog or WASD emulation depending on the title, and Razer's analog-optical switches only behave as true analog in games built to read them; both fall back to simple on/off keypresses in games that don't support it.
