UltraFire 18650 2200mAh 3.7V 4.4A Batteries

While I have had good luck with the Ultrafire products in the past I have not received this order yet. I was hoping it would have arrived after 2 weeks but, I will wait another week and will have to find another flashlight if I don't receive by then.

Sorry about the confusion — that review request email was sent automatically. Since your order includes batteries, shipping usually takes about two weeks. Please don’t worry, your package has already been shipped and it will definitely reach you.
