I have experience with them, very reliable and clean signals, however they use lower quality components, I had a write up on RCFiles but that forum is long gone. They use steel pins which are not gold plated and the frame rate is slower but not slow enough that I could detect the difference.



I'm just pulling numbers out of the air because I can't reference the thread where I recorded my readings, but I want to say that the KO branded Rx was around 5ms and Dasmikro was closer to 10ms, where the SPEKTRUM DX5 Pro is 11ms to give some reference.



Bottom line is Dasmikro is lower quality, but they are good enough for club racing
