I am very happy with this mod for only about $35.
I did my official distance test and maxed out at 1000m in my heavily wooded and wifi congested neighborhood. My distance record before on a good day, was 665m, but usually under 500m. I believe I can still travel plenty farther with this mod, but due to my location, the little spec in the sky that it looks like at .6 miles, is starting to fall behind the trees at the end of my street. Unfortunately trees seem to be the big killer here, and since i do most flying at my house I am very happy i spent the $35 on this rather than $120 on a dbsmods, as i don't think dbsmods would help much more with physical objects coming in the way. I don't have many hugely open areas to fly around me, but I am excited to see now what i can get without terrible interference from my location.
