I have tried various wireless DMX offerings over the years. They vary in price for sure. But more importantly, they vary in reliability. I hated them all until now. The several different ones I have used before were all laggy or worse, totally unreliable. These City Theatrical Show Baby wireless units are awesome. Easy to use, fast and reliable. I’m a huge fan of them now even though they are a bit pricier they are totally worth it. I gig alone, so the gear has to work 100% of the time. I cannot debug during the show.
