Bummer! Ah well, still looks like a great headlamp, especially for the price!
Anyone know if the Keeppower 3400s fit ok in this headlamp?
They fit.
Great! thx.
Wasn't surprised when flat-top cells didn't work in my headlamp with Nitecore's passive polarity protection thing.
Nevertheless, I've had it for a few days and used it extensively and find that it's not too heavy at all.
This may be supplemented by a good head band and soft mount, but never once did I feel like there was a significant mass on my head while chasing crabs or going for a midnight run.
Using a NCR18650A protected, I got 1hr 40mins on highest high (claimed 565lm) which is significantly longer than I expected.
Full review coming soon.
Great news! Looking forward to a review!
Out of regulation...Honestly, I don't see it. Call it ignorance, but it seems as bright running of a battery that has burnt an hour, and a fresh one.
The button isn't stiff. Grow some muscles.
The UI. Yeah, I have to agree that it isn't the most intuitive part of the light. But come on, it really isn't that bad. 30 seconds of glancing over the manual and 5 minutes of play time and it becomes like second nature.
The glowie tail switch makes it all worth it. 
+1, really overclocker, LOL.
I took advantage of this great deal and bought three. Before you judge me, I only did this after I found out that my long lost brothers, cousins, sister was a Nigerian Prince who just died. Just send off my Western Union, now waiting on my good long lost family member to tell me where to pick up my check.
I followed your link, and got sidetracked and ended up looking at some anit slip mats, the ones that FT sells for $1.10, for $8.50 :
I bought a bunch from FT, and I can assure you that these items would not stick as in the picture.
I just glued a strong circular magnet to the tail cap end so that I can work with my beloved headlamp in my workshop
I like the way it looks!
