A great video review of the Revolve system was recently posted to YouTube by a company called Yardbless Pro Shooter. The review is very well done, and offers an excellent demonstration of the Revolve dolly. The audio is in Spanish, but English captions are available by clicking the "CC" button at the bottom of the video.
Yardbless Pro Shooter puts out some very high quality informational videos about video production equipment. Check out their YouTube channel for more great content!
A big thanks to Yardbless Pro Shooter for the review!
