Did you try pressing the switch at the edge? Mine works that way
That switch issue sucks… 
Glad mine is okay.
Right! You can have a $100 light but what good is it if the $.10 switch doesn’t work…
Yea I really like this light over the Mi7 but this weak switch is so disappointing. 2 out of 10 has faulty switch by far.
Yeah i like it more than the MI7 too.
Although the MI7 is a really elegant little light, a bit ‘girly’ almost. :disguised_face:
I’ve got one be here in couple days. Hope switch Gods are on my
side. 
BTW: Mine shipped Int Bridge. It arrived in US, of all places,…HUNTSVILLE ALABAMA ! I looked it up. There’s an International Airport there.
Never had a shipment from China enter the country this way. ALL packages last 5 yrs+ have entered from San Francisco, Chicago, and NY. First time for everything they say.
Same here. It took 11 days from ordering to arrive. That’s pretty good for an extra $2-3. Although, it was before the lunar new year.
FYI, the button is good on this one, woohoo!
Is it brighter than the MI7?
I had the whole light apart and on my bench the switch worked fine.
Encouraged I changed the mcpcb to a dtp one (spent one hour filing down a 16mm one) and put in a 219C 90 cri led.
Then put it together, aligned the switch and still have big problems with the switch
Maybe if I find some motivation to work on this light again, I try this method
Or maybe I put in a new switch, does anybody know which one does fit?
No, i think the MI7 is brighter.
But i almost immediately put a Nichia 219C 3500K and a TIR optic in the UT01, so i lost some lumens with the LED swap.
(but gained a very pleasant tint 
)
GeeSuS Christ….been in Alabama for over 2 weeks now for all I know and not one update to tracking. International Bridege gets the SUCK AWARD! WTH ! Looks like I will have to request NO IB SHIPPING from GearBest in the future. This is the second time this crap has happened……no more in future…Shame on IB !!

I don’t see any pics in the review.
Unfortunately sli.mg deleted them .
I have re-uploaded them , i just need to fix the image links . Today or tomorrow i will do it .
Why is anybody of the belief (which has probably been offered previously) that ANY “tracking” originating from (???) is not only legitimate but connected to a package that was actually ever sent?
When you’re already forced to wait 60 days before somebody will quit sending the same old tired answer to simply switch to another demand asking that you send even more money…why in the world would one believe that any package was even sent in the first place?
Again, a “tracking number” from “who” owned and/or controlled by or in cahoots with “who” with a longstanding record of “what” ???
LOL…so never order anything from anybody and never fear… :laughing:
If “fear” of actually receiving anything from ??? is ever a factor in ordering…good advice.
According to buddas reviews the E11 / UT01 emits more OTF lumens.
750-650 Lumens
Versus 587-527 over roughly the same time duration…. first 3-4 minutes after turn on.
The reviews were posted 2 months apart. Some variables could be measurement methods, condition of the batteries after 2 months of use, random sample variations…etc
taken from here:
It should also be noted that the Klarus despite being dimmer on initial burst, remains brighter for a longer duration (10 minutes extra). It is also better regulated over that time as the 14500 depletes. So the E11 and UT-01 sacrifice run time and regulation in favor of initial turn-on burst (775L). So after ~7 minutes the Klarus becomes the brighter light.
pics ok now
My UT01 DOA.
Not work with any battery With battery it consumes 4.8 uA, no reaction on button press, nothing…
