OLight M21-X, 2x AW 3100 18650, 2x CK 3100 18650, 1x battery Tube, 1x Surefire Charger 18650 Batt Combo purchased before I knew they were unreliable. Might relegate that one immediately to the trash can, as I paid less for it then it would cost me to ship it back and get a refund. Excited about the M21X, though. Looks like an awesome light with a decent range and nice spill.
