ok.. I got mine last Friday....
after first charge... I was after 8 of constant use: calls, texting, navigation, bluetooth, Pandora all day. I mean it was on constantly! (for those that dont know, Pandora is an internet radio!)
It is still going strong.. today is 3rd full charge. I will use it regularly. Not pushing it. And see how it does.
my opinion: For $10
It is a must buy!!!!!
Worse case senerio:
It is a great backup battery in emergencies.
even if it gets worse over time: and becomes 50% of the stock battery. Take into consideration: if I purchased one of those backup chargers thingies that use four AA batteries. Those things cost about $15 plus the cost of batteries. Never used one.. but i would think it sucks and the bulk and hassle.
