Pros:
I'm using this driver to drive a CREE XR-E P4. The driver looks well made and pretty compact. 17mm is about the right size for most 16340/18650 based flashlights. Driver works with either 1x18650 battery or 2x14340 batteries. With 2 batteries the led is brighter but generates more heat. with one battery the LED says cool but is a bit dimmer. I have also tried this driver with a XP-E R5. This works fine with two batteries but with one battery the medium mode flikers randomly ones the battery drops to 3.7v.
Cons:
A bit dim when used with one li-ion.
Other:
Does work with XP-G R5.
Bottomline:
Good multimode driver for single LED.
