"Great headset, worthy update from Jawbone"4.5 starson by ManTiki2go
Pros: Easier to use due to button and voice commands, looks professional, call quality is good.
Information service is better than the V1 was, this one includes live traffic info and GPS directions into your ear.
Cons: Battery life not great, but just fine for normal days
Summary: Had a V1 in the past, then lost it and used a Jawbone I was given as a gift. This is much easier to use. Always had problems with the Jawbone staying on the checking and using the buttons under the skin of it.
The voice commands are nice, Caller ID is useful for closest numbers you know, and it's simply a more advanced headset that other ones that cost the same amount.
I have noticed the comments that some broke so have been careful not to carry it around with my keys in my pocket.
I also like the different Information service it connects you to where as the V1 connected you to Google. This one gives you live traffic information as well and can route you to your destination after telling it where you are and where you want to go. Very handy while driving.
