Anyone looking for a small compact flashlight is right here. The E12 has a tactical on / off switch and three modes that you can switch on the on / off switch with light pressure and all with memory function. All you need is one AA battery, which are very common and the small E12 shaft in Power Mode 130 lumens. The dimensions are doing so, I have rather small hands and it fits perfectly. I can recommend the E12 quite clear on. The shipment also went afloat with me.
