This is, by far, the BEST bluetooth headset I have ever owned. I've tried all the Motorola ones, and they pale in comparison to the Plantronics. You can see by all the positive reviews that this thing is amazing.  I can walk all over my house while my phone is in one spot, and talk without any interference.  The only problem is that I always forget where I put my phone!  The range on this headset is truly amazing.
