A few months ago, Vimeo member HDSLR NOW showed a video review on the Trusmt D100 matte box (seen here), and this time Joel is showing features of the new Trusmt D140.
It's a larger sized Matte Box but provides many more features over the D100 that some people might require. There's not much more I need to say as the video is pretty detailed in all the specs. [Thanks Joel] Trusmt video gear can be found on it's eBay store (click here).
