Review on Neewer 60cm Aluminum Alloy Camera Track Slider Video Stabilizer Rail with 4 Bearings for DSLR Camera DV Video Camcorder Film Photography, Supports up to 17.5 lbs/8 kg by Shahed Cleveland

This 80cm rail fully stabilizes my camera and makes for very smooth movements when shooting video. The slider is so versatile with its angle adjustment. I mount it on a single tripod in the middle for lighter cameras, or mount one at each end for even more stability on my larger ones. The siding has threaded holes to mount the airframe on either side vertically or diagonally above the stand or below under the stand at ground level. It has built in liquid balancing with resistance. When the bubble is in the center, you know it's balanced. Professional high quality slider and good deal!
