Open Glow is better than I expected. Good UI with click-on/off and lockout, 4 levels plus tip glow, detachable etc. Drop-in charger works for me but they took the usb off. Could be little shorter and laser (press and hold to come on) is decent but could use upgrade for better outside visibility. Flag version coming and the I3t is better than I thought. Free walking light/flasher good too!
Unbelievable Upgrades: Olight O'Pen Glow v O'Pen Pro-this pen is WILD!
