To me the Clicky represents a wonderful light and certainly one I'd be happy to carry if I did not own a McGizmo. However, I would always pick a McGizmo over a Clicky for several reasons, and you shouldn't believe for a moment that I'm exaggerating... these opinions come from nearly half a decade of McGizmo EDC:
+ Don's pocket clip is the best in the world, in both retention, carry comfort and ergonomics
+ Don's reflectors are the best in the world, the smoothest and most balanced
+ KISS (keep it simple, ) UI
+ perfect ergonomics for comfortable use over both short and long periods
HDS and McGizmo tie for me in several areas:
= durability... while HDS is unquestionably designed to be durable, the McGizmo certainly holds its own, I would claim them to be more so than Surefire thanks to thick body walls and titanium construction
= output... neither claim to be the brightest, but both are sufficiently bright
= converters... Don always picks some of the best converters in the business to use in his lights... Henry MAKES some of the best converters in the business to use in his lights
McGizmo fails in some areas:
- expensive
- limited, so may be hard to replace
- theoretically less versatility (but honestly two or three modes have always been enough for me)
My latest, most comprehensive opinion on McGizmo lights is here:

As far as I'm concerned, a McGizmo is the best EDC money can buy.
As far as the Spy007 is concerned... add a pocket clip and perhaps even better water resistance and maybe it can contest McGizmo for my pockets. No offense to Data of course, whom I respect most highly out of anyone I've ever met.
