I just noticed this yesterday on their site. Basically a custom syringe-based vacuum system to fill cartos. Valet This looks pretty interesting. I've often wondered if it was possible to use some kind of vacuum system to suck juice into a carto, and looks like they have done it with a syringe and some custom caps that allow you to fill a carto directly off the bottle and push the excess back into the bottle. Not sure how well it would work with a punched carto, although it looks from the video like the silicone caps would cover the carto punches. I haven't measured them, but the JC Vea cartos seem to be about the same size as a regular 510.
