FeiyuTech VB4 3-Axis Smartphone Gimbal with Built-In 8.5in Rod

In this review of the FeiyuTech VB4 Kit, the bottom line is straightforward: this compact 3-axis gimbal is best for vloggers and casual filmmakers who want stabilized phone footage with minimal setup and a longer shooting window. The reviewer found the VB4's built-in 8.5in extension rod and AI face tracking to be the single biggest reasons to consider it, since they enable hands-free framing and creative angles without extra accessories. Battery life and portability make it useful for day trips and longer live streams.

Key Features

• AI Face Tracking & Gesture Control: Enables automatic subject follow and hands-free operation for solo creators and livestreams without relying on a phone app for basic tracking.
• 3-Axis Stabilization: Uses a high-precision gyro and stabilization algorithms to reduce shake and deliver smoother handheld footage across walking and travel shots.
• Multiple Shooting Modes: FPV, Pan Follow, Tilt Follow, and Lock modes provide flexibility for vlogs, action clips, and smooth cinematic pans.
• Built-In 8.5in Extension Rod: The integrated rod expands framing possibilities for low-angle shots and wider group selfies while folding down to a compact 6.3in form.
• Bluetooth App Control & Expansion: Connects to the Feiyu ON App for panorama, time-lapse, and dolly zoom functions, and a USB-C port accepts optional modules like a magnetic fill light.
• Long Battery Life: The internal 950mAh battery runs up to 6.5 hours, suitable for extended recording sessions away from power.

Who It's For

The VB4 is aimed at social video creators, vloggers, and casual filmmakers using iPhone or Android phones who value portability and hands-free tracking. Its compact design and built-in extension rod make it especially handy for solo travelers and content creators who do a mix of handheld and selfie-style shooting.

It is less suitable for professional productions that need heavy payload support, advanced camera controls, or multi-accessory rigs; users who require rock-solid mechanical precision under heavy phones should consider higher-capacity stabilizers instead.
