I have just recently had the pleasure of purchasing one of these cases and I somewhat enjoy it. I say “somewhat” because unless I have a defective case the battery doesn’t maintain a charge as long as quoted. Also, mine takes longer to charge than they hour the packaging says it does. Along the side are four blue lights that are said to indicate battery percentage. On mine, immediately after removing charging cable the 1% indicator lights up, yet the case continues to. Barge for roughly 5 hours. The case is a great idea if you happen to grab one that works. Included along with the case is a standard USB cable for charging and syncing.
