Seido Battery

[nootrak4]

I'm really thorn between getting an extended batter (because it makes the phone bigger then what it already is) or this battery which they packed other 250mAh. I would really like to know if that extra 250mAh really makes a difference and how much of a difference does it really make. I know this battery are expensive but i rather get something that will work.

thank you
