Beitong Reviews: What HLPLANET Found Testing the KP40D and Kunpeng 20 TMR Controllers

Beitong (BETOP) is a Chinese company that has made gaming peripherals for over 20 years, mostly for its home market, and now sells worldwide via AliExpress. HLPLANET (hlplanet.com) has reviewed two Beitong controllers, the KP40D and the Kunpeng 20, and compared the KP40D head to head with the Flydigi Vader 5 Pro. As of October 2026, both verdicts are positive.

What does Beitong make?

Beitong makes gamepads for PC, Android, iOS and Switch, and its current models use TMR (tunnel magnetoresistance) joysticks. HLPLANET's coverage includes:

• Beitong KP40D: a premium Xbox-layout controller with adjustable stick tension, about $80.
• Beitong Kunpeng 20 (KP20): a budget TMR controller at around $49.
• Beitong Kunpeng 70: listed in HLPLANET's latency data but not yet fully reviewed.

The KP name comes from Kunpeng, a creature from Chinese mythology. HLPLANET notes that Beitong has a long history of making good controllers, but only recently became known for consistently top-tier pads with innovative features.

Beitong KP40D review: is it worth $80?

Yes. The Beitong KP40D review calls it an excellent, well-rounded premium controller and recommends it for competitive shooters, fighting games and platformers alike. The review page carries an Editor's Choice badge.

• Price: $80 base, with accessories such as the charging dock sold separately.
• Sticks: TMR with tension adjustable from about 30gf to 90gf (a standard Xbox pad is about 60gf) and resolution selectable from 8-bit to 12-bit. Taller sticks are included.
• Triggers: Hall Effect, with trigger vibration and a mouse-click stop mode.
• Buttons: optical ABXY switches, a microswitch D-pad, four rear paddles (two of them magnetic and adjustable) and two extra mouse-click bumpers.
• Connection: 1000 Hz wired and on the 2.4 GHz dongle. Gamepadla data shows about 2.5 ms for buttons wired and about 6.5 ms on the dongle.
• Battery: 1000 mAh, roughly 10 hours in testing.

Pros: the tension adjustment, which the reviewer calls the best they have seen in a controller, granular iControl software, adjustable paddles and tall sticks. Cons: no 4-way D-pad mode for retro games, face buttons that can miss rapid presses, a cross D-pad sold separately and a stronger stick center bump than the reviewer liked.

Beitong Kunpeng 20 review: a good budget TMR controller?

Mostly yes, as long as it costs under $50. The Beitong Kunpeng 20 review calls it a great low-cost TMR controller for PC, Android and Switch with many features and strong build quality.

• Price: around $49 on Amazon.
• Sticks: Beicheng TMR modules that felt accurate.
• Triggers: a switch toggles between analog travel for racing and Rocket League and a hair-trigger mode for shooters.
• Extras: two back buttons, gyro and mechanical face buttons.
• Polling: 1000 Hz wired.

Pros: a sturdy, grippy build with premium-feeling quality control, accurate sticks and a long feature list for the price. Cons: cumbersome PC software that took several attempts to launch, back buttons that cannot map to keyboard keys, an uncomfortable D-pad with unreliable diagonals, an inconsistent wired connection, no 3.5 mm jack and latency that is not among the best.

Beitong KP40D vs Flydigi Vader 5 Pro: which is better?

It is close to a coin flip. HLPLANET's Vader 5 Pro vs KP40D comparison prices both at $79.99 and finds each winning only a few categories by small margins.

1. The KP40D wins on sticks, grip comfort, bumpers, fast optical face buttons and a cheaper dock ($9.99 versus $24.99).
2. The Vader 5 Pro wins on software, battery life (about 15 hours versus about 10), colour and accessory choice, RGB and its extra C and Z buttons.
3. Triggers, gyro and haptics are effectively a tie.

The author personally leans toward the Vader 5 Pro, mainly for the C and Z buttons.

How do Beitong controllers compare on latency and tension?

They are competitive but not class-leading. HLPLANET's low latency controllers list includes both the Kunpeng 70 and Kunpeng 20 in its PC table; the Kunpeng 70 posts the lower button figures, and the Kunpeng 20's stick result on the dongle is far higher than its wired result. On tension, the adjustable stick tension guide lists the KP40D range as 30gf to 90gf in steps of about 2.4gf.

Which Beitong product should you buy?

Quick picks by use case:

1. Competitive shooters: KP40D, for tall sticks and tension control.
2. Fighting games and platformers: KP40D.
3. Tight budget: Kunpeng 20, ideally under $50.
4. Racing and Rocket League on a budget: Kunpeng 20, using analog trigger mode.
5. Best software and battery at $80: consider the Flydigi Vader 5 Pro instead.

Key takeaways

• HLPLANET has reviewed two Beitong controllers and compared one with Flydigi; all verdicts are positive.
• The KP40D is the standout, with an Editor's Choice badge and class-leading tension adjustment.
• The Kunpeng 20 is good value under $50 but held back by software and wired-mode issues.
• Beitong's weak spots are software polish and latency that is good but not industry leading.
