Query: Phenomenal!

What can I say that hasn't been said already? I have the Petzl tikka plus (which I really like) but I have to say the XP is head and shoulders above even that outstanding unit. REALLY bright with the high setting and blinding with the boost mode. Great diffuser, high quality construction, nice tilt mechanism. Useful for so many things (i even used mine to paint a dimly-lit area of my apartment!) Hard to believe we used to lug around 3 D-cell maglights...
