I've had the Samurai since they came out. Works great. Start/Stop on Epic anyway works perfect. I'd luck to upgrade mine to the Blade though. Better screen and standard BNC connections. Long Battery life is also fantastic.
It's from RTmotion. They gave me a heads up to whats brewing over there. There's a few more goodies coming from them. Also, response from them can be sketchy at times as they are a very small shop. They're probably busy co-ordinating the large group buy I organized a few months ago :)
Hands down the most comfortable shoulder pad I have ever used. If you can attach velcro to the bottom of your camera, you're golden.

In my search for an affordable wireless follow focus, I pretty much had to decide on the Redrock Micro, or the RTMotion. I decided to go the RTMotion and even managed to get a group buy going over on Reduser. The link is here.
