I originally purchased this Bluetooth device from Amazon in late April. My first bluetooth! After connecting it to my Blackberry 7130e, I was happy. Hands free talking, it was great. People on the other end said they could hear themselves echoing from time to time, but it didn't seem to be too big a deal.Then, in June, it failed to connect to my BB. After calling Plantronics, they told me I had to figure out if it was my phone or their device. So, I got to spend time in the "Technical Questions" line at Verizon. It wasn't my phone, I could connect to other bluetooth devices in the store.I sent it back and receive my replacement around the beginning of July.It just happened again and I couldn't be more frustrated. The technology has failed and not to mention Plantronics sub par customer service which sounds like they have less than educated individuals manning the phones. I'm going to attempt to get a refund, however I'm sure I'm out of luck. I am not going to try this device again. Good luck!
