I was skeptical at first of the power switching, and its abilities. But on further use, I find it appears to work the best out of all the eachine VTX's i have ever purchased, I find its even better than some of the other brand units on here. I have tested the outputs with a RF explorer, at 25mw I get right near the antenna at -35~db, which is almost spot on. at 600mw I get -18db~ which is pretty much dead on also. So works as advertised, Gets quite hot on 600mw but which transmitter doesn't? So i typically run it at 25 for race days, 200 for open field fun, and 400 for sketchy environments :) Works well, cannot complain, the auto lower power output while you adjust settings comes in handy in the pits. and I notice it slowly ramps up its power when you fire it up. :)

First bench test shows this to work well. Very clear picture on my Goggles Two. The range of power levels is amazing. .01mW is perfect for setup and testing your fpv without interfering with anyone else's signal. At this low power level signal is clear for about 10 ft and then disappears completely. I will write another review, or edit this one, after I have flown it. Product picture is accurate and I like the wiring harness.
