Chauvet (DJ), Blizzard, and ADJ are for the most part DJ-grade products with the price tag and performance to match. Their wireless offerings are not professional quality nor should they be depended on for applications that matter.
The OP mentions “professional setting” where flickering and momentary blackouts are unacceptable. As with anything wireless, professional performance usual means a professional price tag. A true “big name” wireless DMX setup can cost thousands but with proper component selection and setup will be very reliable. It’s up to the OP to decide if it’s worth the cost.
Hence my purposeful use of "air quotes" around "big name". It's clear to you and me that these type products are more of a gimmick or band-aid solution at this level, but because an established brand (even if it's not established in the "professional" tier of manufacturers) is behind it people can get burned, much as the case was here.
To the OP, what kind of budget are you working with? Like Jeff and myself have alluded to, there are mission-critical solutions that exist, but will not be cheap. The Iron Triangle is in full effect here.
