The sub-250g drone market is fiercely competitive, with manufacturers racing to offer advanced features at budget-friendly prices. Holy Stone's HS900 Pro is marketed as the company's most capable consumer drone yet, targeting beginners and enthusiasts who want premium specs without the flagship price tag. However, in a segment dominated by DJI and packed with capable alternatives, the HS900 Pro struggles to stand out, delivering a middling performance that feels more like an incremental update than a game-changer.
Design and Build - Compact and Well-Constructed
The HS900 Pro features a typical folding design for its class, measuring 143x82.8x62 mm when folded and weighing just 249 grams. The lightweight yet sturdy plastic frame feels solid, and the included shoulder bag adds portability. The folding controller is compact (152.5x47x82 mm) and houses all necessary controls: control sticks, Return to Home button, speed selector, gimbal dial, and a small joystick for camera settings. The 2250 mAh batteries deliver around 23 minutes of actual flight time, slightly less than the advertised 30 minutes, with automatic Return to Home triggered at 20% charge.

Flight Features and Tracking - Mixed Results
The drone flies smoothly with responsive controls, Level 5 wind resistance (up to 24 mph), and three speed modes: Stable (11 mph), Normal (22 mph), and Sport (31 mph). Automated flight modes include Follow Me, Point of Interest, Waypoint, Gesture Control, and Cruise Control. AI subject tracking has improved over the older HS900, with the Following mode keeping the subject centered effectively. However, the Parallel mode exhibited severe vibrations during testing, a glitch that requires a firmware update. The lack of obstacle avoidance sensors is a notable drawback, as many competitors now offer this feature. TOF and optical flow positioning help in weak GPS or indoor conditions but do not compensate for the absence of collision avoidance. Similar issues with software bugs have been seen in other devices, such as the recent Android 17 bug that blocked Google Wallet on Pixel phones, highlighting the need for consistent firmware support.

Camera Quality - Decent for Beginners
The camera uses a 48MP 1/2.3-inch Sony CMOS sensor with an 83-degree field of view, capable of 4K video at 30 FPS and RAW photo capture. JPEG images are acceptable for an entry-level drone, with decent color and detail in good light. However, RAW files suffer from noise and compression artifacts, limiting editing flexibility compared to rivals like the DJI Neo or Mini 4K. The time-lapse mode is easy to use but requires manual flight control, making it less stable in windy conditions. Compared to the base HS900, the camera performance appears nearly identical, reinforcing the incremental nature of this update.

Verdict - A Solid but Outpaced Entry-Level Drone
The Holy Stone HS900 Pro is a capable drone for beginners, especially if found at a discount. However, the competition now offers obstacle avoidance, better image quality, and more reliable tracking at similar price points.

Without firmware updates to address vibration and camera issues, Holy Stone risks falling further behind.
