Review on ANNSM 31.5”/80CMs Carbon Fiber Rail Rods Camera Slider | Manual Wheel Belt Pulley | Flywheel Drive | Length Adjustable Legs | Carry-on Bag | 18lbs/8Kgs Load | DSLR Cameras/Camcorders by Chris Nonamaker

This slider is well made but the biggest issue for me is that you can't move the slider carriage by turning the handwheel. You can spin the flywheel by depressing the bottom bracket, but there's some sort of slipper clutch mechanism that keeps it from working in reverse. The slider action was a little clunky with no load, but got a little better once my camera, lens, monitor and fluid head were attached.
