To be honest, I'm quite disappointed in Dyno. First, the promo video never mentioned you would need
special rubber bands for it to work, only in the download. I'm not used to sneaky surprises from
Penguin: but okay, I ordered the rubber bands. After a few days of practice, it's a nice little
eye popper when it works, but that's only 40% to 50% of the time. The instructional video is sorely
lacking about what adjustments to make for it to work consistently. I've tried everything I can
think of, but with not much success. Definitely not something I would want to try in a performance.
