Absolutely love this light!!!!!
The light definitely holds a charge longer than most of the lights I have used. I use it on an hourly basis for my job as an hvac tech, in an attic, crawlspace or basement. Great product

"This thing is awesome, I’ve had mine about three month and absolutely love it. I’m in construction and carry it every day. Must have. Thank you ultrafire"

- James Gardiner

"I carry mine exactly like this one everyday. I have 6 or 7 EDC flashlights but I always reach for this one."

- Chip Bryant

"The UV light on the S3 has been super handy for me. I’ve used it at the garage to spot small leaks and check for fluids that aren’t visible under normal light, and even at the market to quickly check fruit freshness. Didn’t think I’d use that feature so often, but it’s actually saved me time more than once."

- Michael Anderson

Bought one to see it’s durability.
"Use it as a secondary flashlight for work. Would love to buy one for my personal car."

- Brown Ken

Cool little light

"Exactly as advertised I use it every shift on the ambulance."

- Stephen Clinton239

I'm that guy that can't stop buying lights!

"But I found the one... This is the best one yet and for the money, buy two!"

- H. Little

Simply excellent
