I have tried out 3 different battery packs/cases for my phone but this definitely is the only one I ended up keeping. It's small and convenient and I like how the charger even has a connection for your lighting usb cord so you can charge your phone and the battery at the same time! it gives me about 40% battery (if I'm not constantly texting or having tons of apps open as i usually do). My only problem is that light up button stopped working? but it's a minor detail...because it still charges and holds charge!
