5 out of 5 eggsBattery Life Rocks!

Pros: Battery life is increased significantly. I use S3 constantly for phone, text, email, browsing, and I can easily get through an entire day with plenty of battery to spare. Before this, I was running on fumes by 5pm. The increased size is not bad -- it is actually a bit easier for me to handle the phone with this battery installed.

Cons: I bought two (for separate phones). The fit is *slightly* less than perfect - nothing bad, but there is a slight click indicating the cover is not fully seated.

Other Thoughts: For $25 this is a deal. Company is great. Good service.
