Must Have


Great light weight pocket flashlight. I use it as my pen light, but numerous times have used it scene lighting inside houses or a flash light when walking into scenes. Small, yet bright. Perfect for the price. Would definitely buy more.

Bright Light in a Small Package!


This versatile flashlight is a great addition to any emergency kit, in a car, or any other off-duty use. Also a great back-up light for on-duty use. I am going to buy one for each of my family members to put in their car or home.

Great EDC Light


I love this light! Its very bright in low light and can be used at a decent distance for the price. The only issue I had was the pocket clip bending on the top most layer. But all you have to do is bend it back. Overall I would buy another one for myself or as a gift.

Compact and surprisingly bright


I love this little light. I am able to clip it into my leatherman belt case. Fits perfect.

Solid flashlight


Great little light. Bought to wear on my belt with my multi tool. It's small enough to fit on the side of the leather man case. It's bright for it size and is a good backup flash light. Always using it for odd ball jobs.
