I have had this bluetooth for about 19-20 months and love it! I've used it with a Motorala Razor, LG Shine & my Blackberry -- it works great! I bought this for my sister, who has a hard time hearing on her cell phone and every bluetooth she's tried, and she absolutely LOVES this bluetooth.I will be buying another one - as a back up since I don't want to be without this device!I'm on my third ear piece (the rubber gives out - but I just started using the third one within the last month, so for 19-20 months of owning the device that I use daily isn't so bad.)
