GameSir Cyclone 2 Review

Most reviews and product listings call the Cyclone 2 a 'Hall-effect controller.' It isn't. GameSir uses TMR — Tunnel Magneto-Resistance — sticks based on the K-Silver JS16 platform with a modified centering spring for stiffer feel. TMR reads position with about 4096 sampling points, roughly 10 times the resolution of standard Hall-effect sensors. In practice you get tighter micro-adjustments near stick center, which is the range where FPS aim precision actually lives.

Why this matters: at $49.99, you're getting the same core stick technology used in the $329 Razer Wolverine V3 Pro 8K PC and the $99 Steam Controller. The Cyclone 2 is one of the cheapest TMR-equipped controllers on the market by a substantial margin. Any review that positions this as a Hall-effect budget option is underselling what it actually is.

The Cyclone 2's triggers are Hall-effect analog by default. Flip a small switch located on the inside face of each trigger — accessible with your index finger without moving your grip — and the trigger converts to micro-switch mode with instant actuation and mouse-click feel.

Compare this to the GameSir Tarantula Pro, which has the same trigger mode functionality but places the switch on the back of the controller. To change modes on the Tarantula Pro, you have to move your grip. On the Cyclone 2, you flip a switch with the same finger you use to pull the trigger. This is a small ergonomic detail with real consequences: you can swap trigger behavior in the middle of a game without pausing. Most $150+ controllers can't do this, either because they have fixed trigger stops (Xbox Elite Series 2 uses hardware sliders on the back) or because they require software toggling.

Both modes work. Linear Hall gives you smooth analog throttle for racing games. Micro-switch mode gives you instant actuation for shooters. The switch feel is clicky and confidence-inspiring. This is the single best design decision on the Cyclone 2 and it's worth calling out because it's genuinely rare.

M1 through M4 sit on the back of each grip. Two per side, easily reached with middle fingers. They map via GameSir Connect (Microsoft Store or the Chinese version with more languages and earlier firmware). No default mapping — you assign them yourself.

Mapping the stick clicks to back buttons is the Xbox Elite Series 2 advantage: sprint and crouch without lifting your thumbs off the sticks. The Cyclone 2 does this at $49.99 instead of $179. The M1/M2 buttons are plastic — not metal like the Elite Series 2 paddles — and feel slightly less crisp under the finger. After 180 hours of testing across multiple reviewers they work consistently. The M3/M4 buttons sit slightly further out and take a small hand adjustment to reach comfortably.

Four remappable back buttons is a real edge over the 8BitDo Ultimate 2's two, and it's the primary spec-sheet argument for spending an extra $10 over the sub-$40 GameSir options.

The Cyclone 2 has RGB rings around each analog stick and in the central Home button. GameSir Connect lets you set static colors, gradients, or reactive lighting. It looks good.

There's a documented bug — confirmed by CGMagazine, The Gaming Setup, and multiple reviewers — where the lighting will start out following your static settings, then partway through a session begin cycling through random colors on its own. Music-reactive mode isn't enabled. Static settings are configured correctly. It happens anyway. GameSir has acknowledged the issue in firmware release notes but multiple firmware versions later reviewers still see it. If you care about consistent RGB, plan on turning it off entirely — which improves battery life anyway.

The 2.4GHz dongle only pairs the Cyclone 2 in XInput mode. If you want the controller to appear as a DS4, Switch, or Android device, you have to switch modes with a Home + face button combination — which then forces a Bluetooth connection. This is a real limitation: the 2.4GHz mode with sub-1ms latency is only available on PC as an Xbox-style controller.

On Switch and Switch 2 you're stuck with Bluetooth latency (roughly 4–8ms depending on host). On iOS and Android same story. This isn't a dealbreaker for most use cases — Bluetooth on modern hardware is fine for non-competitive play — but if you assumed you'd get 2.4GHz's snap responsiveness on your Switch 2, you won't.

There's also a specific bug worth flagging: in DS4 mode, using gyro controls locks up the controller (Niche Gamer confirmed). PlayStation 4 users hoping to use motion-controlled gyro aim in games like Days Gone will hit this immediately. Workaround: don't use gyro in DS4 mode until GameSir patches it.

The D-pad is the Cyclone 2's weakest input. Tom's Guide called it 'mushy.' Multiple reviewers echoed this. It's a plus-shape design with soft actuation, and while it's fine for menu navigation and general 3D-game use, precision inputs — Street Fighter combos, 2D platformer diagonals, twin-stick shoot-em-ups — will feel imprecise compared to the D-pad on a Switch Pro Controller or Xbox Elite Series 2.

The microswitch ABXY buttons split reviewer opinion. Root Nation called them 'a bit too mushy.' The Gaming Setup and Niche Gamer preferred them, comparing the feel to arcade-controller buttons. Both are correct — the buttons register cleanly with low actuation force, but the mechanical feedback is softer than a truly clicky microswitch. If you're upgrading from a stock Xbox Wireless Controller, you'll find these more responsive. If you're upgrading from a Wolverine V3 Pro's mecha-tactile buttons, you'll find them softer.

Buy the Cyclone 2 if:

• You play PC or Switch and $50 is your ceiling • You want TMR sticks — the highest-resolution magnetic sensor tech — at the lowest price it's available • You use fighting games' input on face buttons, not the D-pad (or you use an arcade stick for fighters) • Four remappable back buttons will actually change your play • You value in-trigger mode switches over rear placement

Skip it if:

• You play Xbox in any form — the Cyclone 2 does not support Xbox consoles • The D-pad is central to your play (buy the Switch 2 Pro Controller or 8BitDo Pro 3) • You need consistent RGB — the randomization bug isn't fixed • You want the 2.4GHz dongle to work with DS4 or Switch modes (it's XInput-only) • You use gyro aim heavily in DS4 mode games — the lockup bug is real

Add $6 for the charging dock version ($55.99) if you'll actually use a dock. The aluminum construction and integrated dongle storage make it a genuinely nice desk addition.

The GameSir Cyclone 2 is the clearest example of a controller from an aggressive Chinese manufacturer forcing the incumbents to justify their pricing. TMR sticks, Hall-effect switchable triggers, four remappable back buttons, and 1000Hz polling at $49.99. Two years ago this feature list was $150 minimum. Today it's under $50 and the incumbents haven't responded.

The bugs are real. The RGB randomization is annoying. The DS4 gyro lockup is a genuine functional gap for a specific use case. The dongle's XInput-only limitation means Switch 2 users are stuck on Bluetooth. But if you factor that in and you're a PC or Switch player with a $50 budget, nothing else in this bracket approaches the Cyclone 2's value. Add the $6 dock and you have a desk-charging controller with TMR sticks for less than the cost of a AAA game.

Buy the version with the dock. Turn the RGB off. Enjoy your controller.
