I'm contracted at a local nightclub as an I.T. Manager/Surveillance Director, and my best investment has been the E1B®. I am constantly asked by security guards, bartenders, and police officers that I come in contact with, after they see my little light, what type of flashlight I use. I've dropped it from various heights (accidentally) about thirty times. This light should have been called "The Survivor." It has been submerged in the pool, accidentally run over by my 3,500-pound sedan, even found tumbling in the washer with the pants. Without fail, every time I use it, IT WORKS. I am a very happy customer with the Backup from SureFire.
