BIGBIG WON Rainbow 3 Review

Overview

The BIGBIG WON Rainbow 3 — sold under the maker's MOJHON sub-brand — is a wireless gaming controller built around two pieces of technology that almost nobody else is shipping: capacitive joysticks and a 2000Hz wireless polling rate. Where the industry has spent the last three years converging on Hall Effect and TMR magnetic sticks, MOJHON went a different direction, sensing stick position through a metal-and-coil arrangement with no physical contact and no magnet to degrade. And where most controllers quietly drop to 250Hz polling the moment you unplug them, the Rainbow 3 holds its full rate over the bundled 2.4GHz dongle.

At $79.99 (ASIN B0FY1FTTTG), it sits in the crowded "premium-value" bracket alongside the Flydigi Vader 5 Pro and Beitong's flagships — a tier where buyers expect pro-grade extras like rear buttons, trigger locks, and deep remapping software. The Rainbow 3 brings all of that, plus a few things its rivals don't offer, like gyro-to-stick redirection and macros that can include keyboard keys.

It is not a flawless package. The software needs a translation pass, the face buttons feel softer than they sound, and community threads contain a persistent trickle of connectivity complaints on Windows 11. But the core engineering is genuinely differentiated, and both press testing and owner feedback suggest the headline features actually work as advertised — something that can't always be said for spec-sheet controllers from smaller brands.

Build Quality and Design

The Rainbow 3 follows the familiar Xbox-style mold — symmetrical grips, offset left stick — which is to say it will feel instantly comfortable to most PC and Switch players. TechteamGB's hands-on describes the shell as solid, with a glossy front plate that reads a little cheap next to the rest of the build, but textured over-molded rubber on the grips where your hands actually spend time. The construction quality is described as confidence-inspiring rather than hollow.

The visual signature is the 14-zone RGB array under a cloudy, semi-translucent faceplate, which diffuses the lighting into a soft gradient rather than the harsh dot-pattern many RGB controllers produce. It's the most tasteful version of an effect that is usually anything but, and it can be toggled off entirely with a double-tap of the FN button.

Button architecture is where the parts list gets interesting. All 16 primary inputs use mechanical micro-switches. The bumpers, D-pad, and the four extra claw/face-adjacent buttons come off well — crisp, tactile, clicky. The ABXY cluster is the odd one out: micro-switches sit over a rubber membrane, so the sound and initial click read as premium while the actual press feels mushier and slightly wobbly underneath. TechteamGB calls the result "anaemic" — the one build choice on this controller that actively divides opinion. Buyers who prioritize face-button crispness (fighting games, fast-paced indies) should weigh this; everyone else will adapt within a session.

The sticks ship with removable tips, and the box includes a spare standard set, a taller set for players who prefer more throw, and a flat cover that converts the D-pad into a disc. Replacement tips are purchasable separately — a small thing, but a genuine repairability win on a $80 controller.

Weight sits in the standard wireless-controller range; the 1000mAh battery keeps the profile conventional without the piggybacked bulk some high-capacity rivals carry.

Key Features

• Capacitive joysticks (non-magnetic) — stick position sensed by metal-and-coil capacitance with no contact and no magnet. Drift-free by design, and measured by GamepadLA at a 96/100 Stick Precision Index, tied with the best TMR sticks it tests.
• 2000Hz polling, wired and wireless — TechteamGB instrumented the controller and confirmed it reports at 2000Hz over the 2.4GHz NearLink dongle (slightly higher wired). Most rivals drop to 250Hz the moment the cable comes out.
• NearLink wireless — Huawei's low-latency NearLink protocol plus MOJHON's own algorithm, rather than the generic 2.4GHz stack most controllers use.
• Dual-mode triggers — Hall Effect analog triggers with slide-in physical locks that engage a micro-switch for hair-trigger FPS work.
• Six extra inputs — two rear buttons placed in the grip crease where middle fingers rest, two top-mounted claw-grip buttons, and a four-function chin cluster (turbo, remap, macro, profile switching).
• FN button — double-tap kills the RGB; hold it and the D-pad adjusts system volume, toggles vibration, or adjusts per-stick deadzones on the fly without opening software.
• 1000Hz 6-axis gyro with stick redirection — motion can emulate either stick, enabled through the app, in the spirit of console gyro-aim on PC.
• Full remapping with keyboard keys — any input can become any other input or any keyboard key; macros can chain both, which is rare on any controller at any price.
• 14-zone RGB, 3.5mm wireless audio support, and platform switching across PC (Xinput), Nintendo Switch and Switch 2, Android, and iOS.

Performance

The performance story is really two stories, and they don't point the same direction — which is exactly why the polling-rate headline deserves scrutiny.

The input pipeline itself is excellent. GamepadLA's instrumented benchmarks put the Rainbow 3 at 3ms button latency and 4.1ms stick latency over cable, with an S-grade composite (4ms). Over the dongle it earns an A-grade 8.8ms composite — comfortably better than the Beitong Kunpeng 20's E-grade 37.1ms in the same comparison, and competitive with controllers costing half again as much. The capacitive sticks post a 96/100 precision score with around 2,500 steps of effective resolution in community measurements, right in line with the best magnetic modules. On the metrics that make inputs feel instant and aim feel exact, the Rainbow 3 delivers.

The end-to-end picture is more ordinary. TechteamGB's overall latency testing averaged around 17ms — fine, but not the outright speed the 2000Hz sticker implies. As that review usefully explains, polling rate smooths and densifies input reporting; it does not by itself collapse total system latency. Buyers chasing absolute minimum click-to-photon response will find faster options. Buyers who want rock-steady, jitter-free wireless that never feels like wireless will be satisfied.

In real-world play, feedback is consistent with the numbers. Driving games and third-person action titles are where the controller earns its keep — solid feel, good triggers, "spot on" rumble from the dual asymmetric motors with 255-level intensity scaling. The locked-trigger mode leaves more residual travel than the best hair-trigger implementations, so FPS players who live on tap-fire may prefer rivals with shorter locks. One quirk worth knowing before purchase: vibration disables itself below 50% battery as a power-preservation measure, which surprises owners who first notice it mid-session and assume the motors died.

Battery life lands at roughly 10 hours with lighting and vibration active, stretching to multiple days of moderate play with both off. That's acceptable rather than impressive for the class — the Vader 5 Pro roughly doubles it on the same capacity.

Software

The BIGBIGWON Assistant (PC) and ELITE App 4.0 (Android/iOS) unlock the controller's deeper layers: stick response curves, trigger deadzones, per-button remapping to gamepad or keyboard inputs, macro recording, vibration tuning, RGB zones, and firmware updates (PC only). The depth here is a genuine strength — this is among the most mappable controllers any reviewer in this price tier has handled, and the keyboard-key mapping and macro chaining go beyond what Flydigi or GameSir expose.

The execution is rough. Menu text overflows its containers, and the English translation produces choices like "Close" where "Off" is meant, leaving users to experiment to find features like gyro stick emulation. Nothing is broken, but everything takes a few minutes longer than it should. Community threads also flag a Windows 11 dongle connectivity gremlin that occasionally requires a re-pairing workaround — MOJHON's fix, per the affected owner, never graduated beyond the workaround — plus a power-management oddity where the controller can wake itself while the host PC is off, forcing a manual long-press to shut it down. Neither is universal, but both recur across independent threads, which is the pattern that matters.

Pros and Cons

Pros:

• Capacitive sticks are genuinely drift-free by design and measure with the best magnetic modules (96/100 GamepadLA precision)
• 2000Hz polling confirmed over wireless — rare at any price, unique at $80
• A-grade dongle latency (8.8ms composite) and S-grade wired (4ms) on instrumented benchmarks
• Six extra remappable inputs plus FN shortcuts for volume, deadzone, and lighting without software
• Most configurable mapping in its class — remap to keyboard keys, chain macros across both input types
• Replaceable stick tips (spares + tall set + D-pad cover included), purchasable replacements
• Multi-platform: PC, Switch and Switch 2, Android, iOS

Cons:

• ABXY buttons sound clicky but feel mushy — the micro-switch-over-membrane design undercuts the premium brief
• ~17ms average end-to-end latency is merely good, not class-leading, despite the polling headline
• Trigger locks leave more residual travel than the best hair-trigger rivals
• Software translation is poor; some features require trial-and-error to locate
• Recurring community reports of Win11 dongle dropouts and self-waking behavior; fixes never rose above workarounds
• ~10-hour battery with lighting on trails the 20h+ class standard

Who Should Buy This

PC players who want tomorrow's stick technology today, at a mid-premium price, are the core audience — especially anyone burned by stick drift who wants a sensing mechanism where drift is physically impossible rather than merely warranted against. The no-drift crowd should also read our guide to the best controllers without stick drift for Hall Effect alternatives. Competitive-minded players who value wireless input density (polling smoothness, jitter-free dongle connection) over absolute lowest latency will get the most from it.

Switch and Switch 2 owners get a full-featured wireless option with gyro, which remains uncommon. Skip it if you need Xbox console support — the PC mode is Xinput only — or if your priority is marathon battery life, where 20h+ rivals exist at the same price. Fighting-game players should audition the ABXY feel first if they can.

Alternatives to Consider

• Flydigi Vader 5 Pro ($79.99) — the same price with adjustable-tension Hall sticks, longer battery life, and eight remappable inputs; our review rates it 8.5/10. It polls at 1000Hz rather than 2000Hz but matches the Rainbow 3's latency in practice.
• Beitong Kunpeng 20 (~$36) — half the price, TMR sticks, faster wired button response (1.8ms), but dongle latency is in a different, worse league (E-grade 37.1ms vs A-grade 8.8ms) and its feature set is thinner.
• ZD Gaming Ultimate Legend (~$80) — 3000Hz+ wired polling, bundled charging stand that doubles as a USB hub, and swappable stick modules; the pick if you prefer a dock-included package and don't need wireless peak polling.

Verdict

The Rainbow 3 is the rare spec-sheet controller whose two headline claims — capacitive sticks and wireless 2000Hz polling — survive contact with instrumented testing. Add best-in-class mapping depth, six extra inputs, and a 96/100 precision score, and the $79.99 asking price is easy to defend. What holds it back from a higher score is everything around the engineering: face buttons that feel cheaper than they sound, trigger locks with too much leftover travel, rough software, a mid-pack battery, and a low-grade but persistent hum of connectivity complaints. It's a great controller with imperfect polish, and a clear buy for drift-wary technophiles. 8.4/10.
