Admittedly we have pushed this thing far beyond what it was probably designed for, having mounted a heavy Panasonic DVX200 4K camera on it for some moving vehicle shots. To keep shakiness to a minimum we ran with as few long extensions and brackets as possible. It worked quite well on our camera car, a 90s-vintage Jag XJS. The hero car, a 1958 Continental convertible, had a bit more cowl shake (the hood is about a million feel long!) so getting a steady shot took more planning. The suction cups seems to hold very well, and we did not have any issues with paint damage. I would say it is a great value for the money, even if there are a couple extra unexplained bits and pieces (thumbscrews and washers) supplied with the kit. I immediately dumped the custom-molded inner case structure, because to use it requires you to completely break down the rig to its nuts and bolts. In favor of quicker setups, we now carry it half-assembled in the supplied bag, sans molded foam bits.
