Anyone seen or tried this.  Smitty's recent post got me searching again for a one touch tuning systems.  I've seen the old arbiter and the more recent DTS but this one is new to me.

There are a couple other YOUTUBE vids on this also.

Yep, and probably a hassle with Rim style mounts. The DTS system apparently have spacers to help with rims style mounting but it can still be a problem depending on the specific brand. And at around $30 per head for DTS not something I want to experiment with.
