I've bought my second and third one here at Amazon but the third purchase was a bummer. Seller indicated a new item but sent me a used one. The second one I bought though was a new one and i'm using it everyday. The reason I bought the second one was to replace the first one that I thought got lost. I found it a few weeks later so now I have two. The third one I bought is for my brother. This one just fits me nicely and I even forget its in my ear. I could wear it the whole day. I like this because it has a long time of use between charge. Only drawback is it gets weak signal and causes static if its not within line of sight with my phone but no big deal since they are both on the left side of my body-phone at my left chest pocket and bluetooth on my left ear.
