Review on Optimized Neewer 31.5-inch Motorized Camera Slider: Wireless Control, Carbon Fiber Track Rail with Silent Motor, Time Lapse Shot, Follow Focus Shot, 120° Panoramic Shot. Supports DSLRs with up to 22 lbs Load Capacity by Josh Ulrich

Accessible slider. As long as you don't use the panning feature to rotate around something, you can achieve nice, smooth movements. I replaced my first one because it wasn't moving smoothly. The second is no better. Push ins and outs or carriage moves look great. Update December 2020 - Many thanks to the customer support team for doing everything they can to make this right. This includes a partial refund of my issues. All this to say that I would not hesitate to purchase this or any other Neewer product because of their excellent customer service.
