Currently I am talking with SIYI about reviewing their new Uni7 transmitter and air unit. I have completed my Tarot 680 Pro build with the exception of the TX/RX. I had already purchased a MK32 transmitter which comes with the HM30 air unit when this collaboration opportunity was presented to me. I am waiting to hear back from SIYI marketing. I doubt they will choose me as I am sure they are like most companies and only work with well known YouTube channels. Maybe SIYI will be different. I certainly hope so.
