I have been using this headset for a while now.  It is lightweight and does not get lost easily like those little toy bluetooth earpieces that hang off your ear.  I see people walking around like they have a stiff neck because they are afraid to turn too suddenly or it will fly off and be lost forever.  Not this one.  Sound quality is very good too, just be sure the boom mic is lowered down to in front of the mouth area.  One thing I don't like about it is the battery saving feature.  After about 20 minutes or so of non-use it automatically turns itself off.  You cannot even wake it up by just a touch of the button.  You have to actually hold the power button in for several seconds and power it back up.  This takes about 5 seconds to accomplish, then it has to connect to your phone- another 5-10 seconds or so.  If you are in a conversation on your handset and you want to quickly go to handsfree then you will miss about 10 seconds of conversation while powering up and reconnecting- not very good.  A fast power up and fast reconnect would earn this headset a definite 5 star review from me.  Otherwise it is a good product and only second to the VXI blue parrot.
