I love this product its not to small and not to big the led flashlight works great for leaving work at night or coming home at night the lazer light works great for work presentations or walking a store and pointing out product in the oberhead  I have a iphone 4s it charges it to a full charge once and a half for my galaxy note 2 or my galaxy s3 it charges it almost to a full charge so either of my phone makes it through a 12 hour work day and more  I definately would recomend this product to anybody that needs a extra charge
