Unfortunately it will be going back. Its not really a bad flashlight for $10, but it definitely aint 160 lumens like it claims... maybe something along the lines of less then 60 lumens. Plus, the light diffuses all over the place.
*BTW Costco, I legally concealed carried while in your anti-gun store, and I will also be doing so when I return your product for a full refund. Suck it!
