I just bought three of them and was literally just coming on line to gush over it. I bought one off the bat and once I got my hands on it, another 2 right away.
I cannot stress enough what a GREAT and I mean GREAAATTTT! freaking little light it is, wow!!!. Frankly, I think it does plenty as is on an eneloop and as much as the SC51 probably does when you use a 14500.
It's not like I don't own other nice lights either, I have plenty of Malkoffs, HDS', McGizmos, Kerberos quads, you name it... I have not been this excited over a light in quite a while. OK, I get excited over every dang light, but this light IS extra super exciting!!!
I really like the side clicky, it seems to make so much sense now that I've used it- and getting to the levels is so intuitive, takes seconds to figure out. Click for high, longer click and hold-release for low, Click and hold a bit longer to ramp from off to Medium. Then just double click within the levels to toggle.
Can you tell I like it? I think it's as steal at 49 bucks, don't even think twice about it! I have not been able to put it down for the 2 days I've had it now and it's become my EDC without question.
B0wz3r has it right, does 90% maybe 99% of what you will need a light for, the rest is specialized and you'll know what you need for that- be it throw, or insane flood. He's right, 1400 lumens from a 5.6 amp Quad is not always the right tool. Neither is a dead simple single level Malkoff, sometimes you just need some levels.
Wow.. WOW!!! And on AA's Wooohoooo!!!!
