Review on Cyalume ChemLight Military Grade Chemical Light Sticks by Fernando Ramani

I usually buy blue Cyalume Snaplight Sticks but I got them very cheap. Now I understand why. The description states a shelf life of 4 years from the date of manufacture. They have already expired three years after this date and will not expire until one year later. They also only burn for 10 minutes before extinguishing. Such a disappointment. I will never order again. Even at a good price.
