I've had a PolyStinger® for just over six years. Fantastic at illuminating dark areas inside or outside. Tough, too. I've dropped it several times even from as high as 15' to a concrete floor with no problem. It even survived alongside me in a motorcycle accident. It's scuffed here and there, but still a solid performing flashlight. I'm still using the original NiCad battery and only need to charge it every 2-3 months. This flashlight will continue to serve me for years to come. Thanks, Streamlight!
