I already owned this flashlight and purchased a second one for the house as it’s a great flashlight. Light weight for its size and packs a punch for light. Would highly recommend

Excellent quality flashlight. Easy to use. Flashlight World has great service and orders arrive promptly. Good communication also. Thank you.

This is an amazing flashlight! This is such a powerful flashlight for the size. I do own a more powerful flashlight but it's too bulky so I rarely take it on backcountry trips. Because this one is compact, I plan on including it on all my trips. Also, the look and feel of both the flashlight and the carry case feels very solid! My shipping to Alberta was surprisingly very quick!

This flashlight is excellent

This flashlight is really amazing. I have two other tactical flashlights, so I know good flashlights, and this one is really amazing. It's my first time owning a Klarus flashlight, and I am very impressed. Plus, Flashlight World is great, the price is reasonable and I got my delivery quickly. The one thing I would recommend is to have the shipping be expedited parcel, so you get the flashlight sooner. That's the shipping method I used. The regular shipping, which is free, may take a bit longer. That is, if you live in Canada, which I do. I don't know about ordering from another country. Overall, I am very impressed with the flashlight and with Flashlight World. I highly recommend this flashlight. It's awesome
