i want to add some extra battery life to my vivid but at the same time get a case to make it look somewhat good and protect it... the safepwr 2 case has a 1800 mah battery and has a case built in but some people say that it doesnt add much battery... the 3400 mah extended battery is better and less bulky but there is no real silicon/hard case to go with it and it costs a lot more from mugen. Let me have your opinions.
