The good - It fits perfectly. Unlike most other bluetooth headsets, it is very adjustable, so it fits in just the right spot - for anyone. The volume it fantastic. And it is fairly easy to use, without reading the instructions. As soon as I read the instructions, it will probably become extremely easy to use. The battery life is good, it has no problems making it through two days in my car without recharging. When it connects well, it sounds great. And people on the other end usually think I sound just fine (if not great.) But notice the "when it connects well..."That leads us to the bad: I can't understand why there is so much static and interference. My phone can be on my hip, with my earpiece in my ear and I am getting a bunch of static. The other Bluetooth headsets I tried did not have this problem. This one does not come close to its 30 ft of range. And if I put it in a case, or in my pocket, or even just wrap my hand around it, I usually get a bunch of static. Sometimes the interference is noticable to the person on the other end of the line, other times they don't notice any problem.Final Word - I will probably keep it. It works well in my car, and most of the other important times for me. If I was someone who relied on this non-stop, I would probably return it. For now, it meets my needs (considering it is one of the least expensive options out there. Once the technology improves, I will replace it.
