Query: RAZR Battery Replacement

The batteries were exactly as advertised, they were delivered in a normal timeframe, there were no issues or hiccups or drama with the vendor. It was "slam, bam, thank you, sirs or madams." Battery life is really subjective as everyone's "normal" is different. But life is definitely restored compared to my original 2 year old battery. My experience is use of Bluetooth really drains batteries quickly. But that's a Bluetooth issue that goes away if you don't use Bluetooth. I have no complaints at all with this product.
