I received my order from Amazon and was able to pair my Black Aliph Jawbone to my Samsung Upstage very quickly and easily. The problems started with the first call. No matter whom I called, including my own voicemail box, my speech was cluttered and broken up. I reset the headset and even tried deleting it from my phone. So I called Jawbone. It was late evening and I was surprised they even answrered. The tech on the phone made a few suggestions, which I tried that night but still the headset was not working. I called back the next day and they offered to replace the whole thing. I sent it in on Thursday and received my new replacement (including an additonal power cord and ear attachments.)the following Monday. The new one works great. They said its guaranteed for a year regardless of the retailer.Great Customer Service!!! I highly reccommend this product.
