I purchased those 3 wks ago....used them everytime ive been in the woods since, about 6 x's. Where i hunt, it is SUPER THICK.... let me restate that SUUUPPPERRRRRR THICK!!! Central Florida, swamps, hammocks, cypress domes....lucky if you can see your buddy 25 yrds away let alone spit without it getting on you LOL.... my range is maybe3/4 mile. Now thats clear readable range. Maybe 1-1&1/4 miles broken transmission. I havent found any radio's that operate well with this kind of cover. Now in plain open area's, they work awsome! and i wouldnt doubt a range of 20+ miles. For the $$$ i think they work great. I am never more than a few hundred yards from my buddy anyways so they are perfect. Some of the features are pretty awsome too!
