Review on Neewer 3-Wheels Wireless Video Camera Dolly: Motorized Electric Slider Dolly for DSLR, Camcorder, Gopro & Smartphone – Remote Control Included! by Tony Buckley

Much less than I expected but it's good! Very light, I can't even tell it's in my pocket. I can fold it up and put it straight into my side pocket. This also works very well. No noise, very quiet ride. This is really a great gadget!
