I've used this stabilizer system on several professional video productions and it has greatly increased my production value. I'm selling it because I no longer have time for video production these days. The kit includes all of the original accessories, and all items are in great condition. This video was very helpful in balancing the stabilizer the very first time: https://www.youtube.com/watch?v=I5PPQ8i1xV8 Below is the description from B&H where it was purchased brand new for $1400.

The Birdycam Lite 3-Axis Motorized Stabilizer System from Varavon supports a wide variety of lightweight cameras. It allows you to capture smooth, fluid shots whether you're actively following the subject, or the subject is simply passing by you.
The stabilizer system features encoder 3-axis brushless motors that provides softer movements, and the sealed case and vibration resistant design promote a longer motor lifespan. The PCB board uses the BGC 32-bit encoder controller and SBGC32_12C_Drv expansion module. The locking knob provides faster assembly and safety while filming during movement, and the universal dovetail is attached to the handle and main body for convenience.
