I'm always looking at portable devices. Also looking at the SE Reflexion Filter specifically for using a Royer ribbon which is a figure 8 pattern. I'm thinking this might help absorb the back end of the Royer making it viable way to record vocals with them in less than desirable room. Anyone ever use one of these? Over 200,000 sold already.

At first I thought I was hearing the vocals in the cue and though, erk... but this is abviously the audio coming from their video monitoring so were hearing to room, not the sound of what their getting from this.
