I've noticed some places are selling the E21 and four rechargeable batteries with charger for $34. Does this come that way is it just the light for $24? What I saw was called the "Fenix E21 Bundle".
I currently use this UF 2100 daily for work, the 1 mode though from MF. I like it, bright, compact enough, 18650, durable for ther drops I've given it so far. However, mine does have noticeable rings to it, whether it be looking in elevator shafts, house address hunting, path lighting, fixing plumbing or even the dreaded white wall hunting. (least to most noticeable)
I still edc it, don't get me wrong, and may get one or two for the guys. But if you fixate on rings now on any of your lights... just saying.

thanks for the members support again, here we have 34 members for UF-2100, and 27 members for Fenix E21 now, let's see how many members will we have on Aug 21, and i will give you a coupon to place the order from Aug 22.
I'm in for both, too...
PLEASE???!!!! tell me that you'll be able to hold this out until the 24 (US time). That's payday for me.... 
Please put me in for one Fenix E21, thanks!
Count me in for the Fenix E21 (depending on price)
yes, we will have three days for the members here to place the order. thanks
one UF-2100 for me, please ....thanks
One UF-2100 for me!
Received UF-2100 3 mode today from DD (ordered 30/7). The review on 1 mode from manafont is pretty accurate. Outside finish is nice, reflector and glass are clean, led is well centered, threads were dirty and dry on mine, beam not too ringy and came with SS "attack" ring (only attack thing are sharp threads on it) but:
1) Threads are visually OK, but feel a bit rough when screwing. I cleaned and lubed them, but still not as smooth as they should be.
2) O-rings seem to be too small.
2) Modes. Fresh TF flames: High 1,78A, low 0,09A. Strobe is a bit slow (about 3-4Hz).
any news?Cmon guys!
I am interested for 3 E21 and one 2100.
I'll go with an E21. Thanks again.
Thanks Mikk0 for the information.
Interesting!.DD says 3 modes--> H-M-L. In that case it would be better to have 5 modes version at least to have the Medium. Again its DD.
Summer: Can you confirm this?
Now I feel extremely lucky to have received the 5-Mode!
E21 for me.
Well, we will check much more carefully, and will send the mode 3 items.
well, since we have had a successful groupbuy here, and many members here have already got it, it is no necessary to have the same one the second time i think. But when we have H3 in stock , i will keep all you informed here and make another groupbuy.
in for two Fenix e21's
any chance you can offer the H2 discount this time too?? bummed i missed it.
