We purchased five of these a year ago. First of all the range is not what they claim and most importantly THEY DO NOT HOLD A CHARGE LONGER THAN A DAY. We use them for hunting and have tried charging them with the battery packs they come with, with the USB and other conventional batteries. With the conventional batteries I had to put new ones in daily. I contacted Midland customer service to rectify this situation, as we had spent over $200 on five of these and their response was "Sounds like your batteries are bad." I'm sorry Midland, but I don't think five days worth of batteries are bad. They just didn't want to deal with me. DON'T BUY THESE!! Not only will you have issues with them, but you will be disappointed how the company won't stand behind their own product.
