I was turned on to Sunwayman flashlights by a friend of mine who had a similar model. I was looking for a good flashlight and I liked his. When I started looking at flashlights, I had issue with the multiple click programming to change brightness. Then I found the V20c, the button on the back just turns the light on and off. It has a collar behind the light head that changes the brightness from 0 to 430 lumens and strobe. I carry this flashlight everyday, at home and at work. I purchased two 18650 3000mah rechargeable batteries. I try and swap them out the 1st of the month so i always have a good battery. I have been running this light for over a year and have no complaints. I comes with a fairly well made canvass holster with a velcro enclosure. The belt loop is both permanently attached and velcro attached which allows you to put it on your belt without removing your belt.
