Pros: Bulb Durability, Battery Life, Durability, Brightness
Great Flashlight, Great Price
I was very skeptical at first when I bought this flashlight, not knowing what to expect. What motivated me was the 780 lumen output for the price I was paying. Here's what I like about it:1. Compact, light and easy to carry. The flashlight is much small than you'd expect for the output and from its appearance in the photos. Don't expect to use it physically as a self-defense tool as it's too small and light for that, but you can definitely temporarily blind someone with the light itself at the 780 lumen setting.2. Can be sized to fit your needs. Need a compact flashlight? remove the back unit. Need a light that will last longer? Add the back unit to increase output time - from 2 cr123A lithium batteries to 4 with the back unit attached.3. Output - has many different settings and outputs to fit your needs. At 780 lumens it's very bright and can blinding; I have a farmette in the Virginia countryside and I can stand at my farmhouse window and case the light clear across to the chicken coop (more than 100 feet away) to make sure everything is ok. I can also cast it at the woods near my house and see everything nearly as bright as day. Great thing to have in any wilderness or camping situation.4. Very durable. I've already used the heck out of this flashlights and subjected to all kinds of abuse and it has held up pretty well.I recommend this to anyone who wants an all around powerful flashlight that is flexible enough to use in a variety of situations.
