After seeing the Steadicar at the Stabilizer Expo some weeks ago, I was impressed enough to order it for a scene we shot today on "Key & Peele". It turned out to be the maiden voyage of this piece of gear in Los Angeles. Everything went very well. While the Griptrix offers more flexibility in mounting options (especially for outboard gear such as lights), swapping sides for different shooting directions as well as height is so much faster with the Steadicar that it reminds me of the paradigm Teddy came up with when the first Donkey Box emerged--something like "I'm saving time I didn't realize I was wasting".
For more specifics from an operator standpoint, perhaps Rich Davis can chime in further. Thanks due to Ozzie Silvera for forwarding awareness of the setup and helping facilitate the process.
