I have gone through several Bluetooth devices and this is my favorite by far. I did some research prior and found that if you replace the ear bud with a Jabra ear gel (not the minis) it has a much better fit and sound quality. Some even claim that they are able to go without the earwire (I am not able to do that). My only complaint is the volume control...you must increase the volume in preset increments and then it drops back down to the lowest volume. As for customer service, I found them to be quite accomodating even though I did not purchase the product directly from them.
