Review on GVM Camera Slider, 31”/80cm Carbon Fiber Dolly Rail Track Stabilizer – Sturdy Video Shot Slider with 6 Bearings for DSLR Camera DV Video, Movie, and Photography by William Obong

You can get good results, but it takes more effort than it's worth. Build quality seems good at first, but once you add a camera there is so much play in the mounting plate that it's impossible to get clear shots. This leads to very jerky movements even in loop and parallax mode. Because there is too much play, the camera doesn't start rotating at least 5-7 inches. And it's so annoying that you want to throw something across the room. It's also almost impossible to repeat shots as the head rotates easily or doesn't stay in the desired position. Be careful, you can get some good shots, but you'll have to work 10x harder than you thought to get them. In addition, the remote control was very. Interesting. Not very user friendly and at times it would flip as if I was looking at the screen from the inside. Seems like a cool effect, but not something you want to bother with when setting up a frame. It seemed to go away when I unplugged the battery and then plugged it back in, but it led me to believe that this thing wouldn't last more than 1 year if that were the case. All in all not worth the headache in my opinion. Great idea, bad execution. I would wait for the next model and hope they fix these issues.
