Review on Neewer Kilograms Capacity Rotatable Camcorders by Ron Turner

The rollers appear to be sturdy, it would be nice if they included a pusher as shown on the packaging. Use it with the 5DmkII with battery grip and 24-70 lens, Manfrotto ball head. It's a heavy unit but it holds it up, if I lean too much it tips over, probably remove the battery grip to get a lower center of gravity
