This battery does not disappoint. I have very few complaints as well about this battery. I liked the versatility with a flashlight, laser pointer, and an external battery. I would have liked an easier way to access what you want. While it says in the manual how to access each of the lights or the battery, it does not work perfectly. The laser pointer works the best because its just a touch of the button. The LED light is the worst because you have to turn on the battery itself before you turn on the light. It just makes for a difficult and confusing experience. Maybe providing two buttons (one for the battery on/off, the other for the lights). This would just make for a better experience with the battery/light. The idea is great and I love it because it hits a large market for people who present with a laser pointer and travel. I also really like the design is great. To make it better (and anything better) I would try to make it thinner. I really like the way it fits in hand. FInally, the LED lights are spot on and work like they should. But one problem I just ran into is that I had 2 LED light is like your last 20% percent. When my battery hit 1 LED, the charger shut off. While I charged my iPhone 2 times from 30% and another iPhone from 27%-57%, I still would have liked to have more knowledge of how much battery I have left. With that being said, the battery still works perfectly and I love it. The fact that it comes with a pouch and other cords is great for the owner of the battery.
