I was on a road trip and I forgot my bluetooth. I just happened to be doing the wash and found a cell phone store just a few stores down so I went window shopping and found this LG hbm-810! It was just put out on the shelf that day so the clerk didn't know that much about it but what I saw and read, even at full price I decided to buy it! Well, 2 phones later and it's still my favorite!! SOLAR POWERED is one of the main reasons why I bought it. I have bought some of the highest quality bluetooths made and this LG is what I'm sticking with!!
