I have an M61T MD2 and it’s awesome! The throw is amazing. It has saved me and my little dog from skunks more than once. I like my Fenix PD35, it has a huge spill but after someone told me about Malkoff I had to have this spotter. And I agree with the previous poster; malkoff tells it like it really is regarding run time and lumens. Btw, I dropped this flashlight on my concrete patio last year and it damage the optics. I called Malkoff and spoke to Todd, really nice guy. They fixed it for free. Since then I purchased an MDC HA TAC that uses one CR123. It replaced my Fenix PD22, which I lost. Figured I’d upgrade. It has great spill and throw; it too is good for keeping an eye out for skunks. Gotta love guns, knives and flashlights.
