Def keep us updated! I just saw on their site that the extended battery is coming soon, can't wait! I bought one of their ext batteries for my original HTC Inc and that thing was a beast! It did add some hefty bulk to the phone but I didn't mind. Curious to see what the design will be for the S3. Hopefully nothing outrageous while keeping the beauty of the phone intact.
I had their battery on my SG2 with a mugen battery, the mugen repeatedly out do them on every test but not by much. I think the cover on their Sg2 is a lot better than mugen. For the price they are good.
