I recently purchased the E05 and it is absolute beast for its size and price! Only thing that I wish is that it should be a tail switch.
Wuben E62 Pen Light - Best EDC Pen With Flashlight
Great quality high intensity flood light. Super bright strobe .
Dose everything it is advertised as being able to do .
I like the pen but even since I received it the only time the light works is if you plug it in, it won't work off the charging cord. I would have given it 5 stars if the light worked.
Super light in a ridicously small space!
This flashlight was as expected and great value
