I don't like writing reviews without testing thoroughly. I put it in a 3 inch Li based tooth fairy, Speedix GS 25amp 4n1. I tested on all MW and never got better signal after 2nd power setting which is 25MW or 100MW. When testing in the 600mW range, my meter only showed 191mW at its maximum range in each range. I was able to escape to an open space, perhaps to a soccer field, before the video squeaked. Tested with short and tall Axii and TBS Triumph. The goggles have the latest VAS Ion and True D 3.8 settings. My 200mW Unifier was 10 times better, the 200mW Tramp HV is also much better. Rush vtx at 200mw is much better. It was very disappointing to be honest because every AKK I've used has been as good as Unify or Vagrant when they have really good ground. MAYBE I HAVE BAD. I want to reiterate but I wouldn't buy without confidence that they work well. The video can be seen on YouTube and Instagram
