$30 lets me out. There are too many lights under $20 that suit me, and I prefer AAA for EDC.

I think the sliding defuser looks cheezy. Plus the crappy UI. I’m out
When a real review from a BLFer known to do objective reviews pops up it probably will be talked about.
There is something interesting going on here. It was discussed recently that manufacturers send out a dozen of the same lights for review. So you get a dozen threads of reviews of the same light in the non commercial section. This works as advertising, apart from whether the content of the reviews is unique or not. Manker sent a bunch of E02 lights not long ago, and there was a lot of discussion of this light. Now Manker did not send a bunch of E03 lights, and there’s practically no discussion. Of course other factors may play a role as well, nevertheless this is certainly an indication of the power of advertising (in whatever form).
In comparison to something like the Fenix MC10 that has a flip up diffuser attachment II think it is a pretty interesting idea. It allows for a diffuse beam if the situation calls for it. If not, it can be slid down for a more traditional beam pattern or removed altogether so it is not in the way. I'll agree with you that the UI is maybe not my favorite. I wish the mode sequence repeated from moonlight to turbo rather than reversed in order once turbo is reached.
In general angle head lights take a back seat to the straight shooters from a popularity standpoint. It seems like its always this way. A lot of people find them ugly and impractical. Depending on how you grasp them, they can be awkward to hand hold (IMHO)
The Fenix HL10 implementation of a diffuser is much better, as it just rotates around the tube.
I think they should have used a TIR, especially with those modern tint shifting LEDs.
Yeah IMHO they could have integrated the sliding diffuser a little better into the overall design. Looks kind of like an afterthought. Still though, an ad-hock diffuser is better than no diffuser. There are times when near-field flood lighting is very nice.
One thing I have found with headlamps is TIR, flood-beam and “mule” optics can be a hinderance when around other people, since you can’t effectively aim them away from peoples eyes. I used a zebralight for 7 years, and it was great… but I found it too blinding for other people when they caught a glimpse of it with night adapted vision. I switched to a TH20, and with its small parabolic orange peel hot spot I find it more practical. As a boy scout coordinator for my sons troop the last thing I want is the troop having to look away when I’m re trying to communicate at night. And we do a LOT of activities at night!!!
I still use the Zebra clipped in my tent as a lantern… where it really excels.
I am waiting for a review of the Nichia version.
Lumens and CRI are still unknown, or?
And a Skilhunt H15 cost the same and is 2cm longer.
If I understand the UI diagram correctly you can switch back to the normal modes by a double click.
So a 2x click switches TURBO on and off.
Seems you can buy one.
It also cycles: Moon, low, mid, high, mid, low, high, moon …
It doesn’t jump from high to moon.
Looks like they changed it from this.
I’d still wait for a review to make sure you don’t have to cycle through the blinkys first. Even if it can go back and forth, it’s still looks strange. Lets say you’re in medium mode and want to go to Turbo. You double click and it takes you to strobe? then cycle through the blinkys to turbo? Or you shut it off, then double click to turbo? I don’t know, makes no sense to me.
Well Turbo has number one, if you switch it should start with Turbo. As I see it’s the same UI as the E02 with an added High mode.
You could ask manker for a review model 
Manker posted this UI diagram
I assume it is the same UI as the E02, and IMO that UI is absolutely fine. It is way ahead above what we were used to not that long ago, which was: high, mid, not very low, blink. With terrible 200Hz PWM. The E02 (and E03h) has a nice low moon that is even user-adjustable, no visible PWM, and how you like the way the modes are arranged is a matter of taste, I see no blunders (like in the S42 UI).
Turbo=double-click from any mode (including from ‘off’ ) , and double click again to get to the previous mode. When in turbo, a single click gets you in the sequence of blinky modes.
A long press from any mode is ‘off’ which is ok for me because Manker’s long-press is actually quite short.
Wether you like or not that turbo is not in the main cyclus is up to you, I guess the idea is that you are supposed to use that light level as something special, which may be fair enough for the rest of the world but perhaps not for the average BLF-member
My gripe with turbo from using the MK34, is that after step-down the output is about the same as high, however you’re still in the second group. After a couple of minutes of using this output I often forget that I’m still in the second group, so a single click results in strobe which I don’t expect.
I prefer that after step-down, the light goes into high mode in group one.
But on how many headlamps do you have high CRI Nichia and a on how many headlamps can user program the moonlight with option of 21 levels. My guess is none except Manker’s. Not even, Zebralight or Armytek headlamps (far more expensive) can give you that. I have Zebras and Armyteks but still like both Manker headlamps a lot - just hope they will make 18650 version as well. :+1:
It’s very heavy for its size, the 350 claimed lumens is wrong & the headband is terrible ,my zebra light h52 is a lot lighter , much brighter ( proper 300 lumens) & the headband isn’t like a piece of cardboard
