Decent VTX at a decent price. I like the mounting holes that make it easier to mount on your stack. I don't have a power meter or any other reliable way to measure output, but it seems to be on par with other 1W VTX's. No microphone, however I rarely use the mic feature on others that do have it.

I use a bunch of TBS Pro HVs, and Rush Solo's dimensions and mounting options are basically identical. That being said; I tried this out for the $20 difference and I found it to have a simplified design in comparison, with the bonus of having 30x30mm mounting holes and a streamline heatsink. The button is sensitive and the led indicators are difficult to see indoors so I'd assume impossible outdoors. But if you're switching with SA, which Diatone includes a detailed user manual to setup your VTX port (IRC Tramp) then its no issue. Video is great so far @1mile comfortably. Haven't tried max power yet.
