Love the pocket size. Great durable light to have camping
Best there is!
Review by Devri V.
Verified Buyer
Have used this light for years! Also, as an aircraft mechanic, sold many of these lights to felllow mechanics. Easy to keep in your pocket, you just have to keep up with it, it's invaluable to a mechanic in his or hers line of work. So handy day to day, can;t imagine being without one. Very reliable!
I have several of these great little flashlights.

On/Off button gives too much resistance
Review by Kamea Z.
Verified Buyer
The on/off switch gives too much resistance. And ten months after I bought it, it has become unreliable, i.e. the light goes off after being on for 10 seconds (approximately).
Great light !!
Review by Gidget J.

The only reason I bought this light is because I lost my other one. I was so upset about it that my wife said quite complaing and just by another one. Can't say enough good about this light. I have it in my shirt pocket whenever I am working on a project. I also like the hat clip. That comes in handing so I can have both hands free.
Bad Button

Cool little light

Very well made and convenient to clip on a shoulder or hat. Good illumination too, worth the price.
A must-have for everyday carry.
Review by Tanga P.
Verified Buyer
This is about the perfect light for everyday carry. This AAA version is shorter and lighter than the rechargeable version and I prefer simply installing a new battery versus having to recharge. It is sufficiently bright for practical purposes in everyday life.

This AAA model has on/off and that's it. No fumbling around with different modes. No nonsense. Pull it off your pocket and hold the button for momentary or click it in all the way to keep it on until you click it again.

Here's the homerun: the 2-way clip that allows you to clip this to the brim of your hat for an instant headlamp. It's light enough to not pull your hat down or otherwise be a nuisance. The rechargeable model, in my opinion, has too much leverage and will cause the brim of your hat to drop.

I've lost probably 6 of these over the years and I always order a new one immediately. It's that good. Oh, and it's cheap too compared to other brand-name flashlights.
Amazing compact light!

I have this light at work. I am amazed with the quality of lighting it gives me while I inspect for the smallest damages to product. Purchased this for home use and take it everywhere with me. You can never spend too much for quality lighting.
