I've enjoyed using this wireless system so far - with minor user experiences they could improve in the future. The USB-C power port in the back could be better by not being so deep into unit; some USB-C cables don't fit properly/easily comes out. It seems to hold a signal well, and finds it again fairly quick (10 seconds) if it drops. Outputting to IOS devices is a GREAT feature. For the value, this one is a keeper. Although I'd recommend using SDI rather than HDMI because it the latency does get pretty noticeable (especially for focus pullers).

For the price of the product it is amazing. It gets amazing reception… well over 100’ through walls. Their customer service is spot on. I sent them an email telling them my pros and cons of the device, and they were receptive. A lot of the cons they say they fixed in the 4k transmitter, but I haven’t worked with that one yet. However, I did use the one before the 400s and it was awful. I could stand right next to the transmitter with the receiver and it’d cut out. Reception is quality on the 400sMy main pros:-price-the build is pretty durable-love that people can tap in with the app while also using the receiver-love that I can change/select channelsCons:-ports/cable inputs are a little all over the place. Makes for weird builds sometimes-they really need a 2/3 pin lemo power option-fan is loud-image can become blocky and hard to pull focus from if the device gets hot (think like direct sunlight middle of desert summer hot)
