Last car part: My Mazda CX-5 2.5L AWD 2015 Touring. I love it so far! Nothing at all bad to say, and very happy I got rid of my Jeep!
Last firearm part: Surefire M300C weapon light. Very bright, GREAT! contrast, awesome throw. It's going on my 14.5" carbine and I think it's a helluva light!
Last computer part: My complete PC, back in 2011-ish. I can still run WoW with most of the settings set to Ultra, and the frame-rate in Orgrimmar hovers around 30. Not shabby!
Last supplement: Pyroxamine. I have dropped around 12-15# (depends on the time of day I weigh) in the last 40 days, and all my lifts are fine. I am still repping out with 315 on deadlifts, and benching 100# dumbells on the flat-bench for 6-8 reps as my last set. Body weight went from 205 w/no clothes to around 190 with no clothes.
Last random item: Energizer L91 Lithium AA batteries. They power my XBOX1 controller several times longer than do regular batteries, and Lithiums don't leak very often at all (if ever).
