Well that’s excellent news there! Such an experience only enhances enjoying the light I’d say. :partying_face:
UPDATE: Manker direct replied very quickly to my E02 issue, and they quickly sent me a replacement, which arrived today. 
They have among the quickest and best customer service of any manufacturer i have purchased from. I give them a high recommendation.
I just got an Eo2 last week had the same trouble trying too get it unlocked,almost two days (and the UI’s not that hard)and it unlocked.I sent Manker an email told me they had never heard of that problem before.A couple emails later they told me to send a video,which is not that easy for me no phone or the such only a desktop computer.I think my lights are higher tec than most any thing in my house (lol),was going to have one of my kids help me make a video to send tried the light a few more times and it came back on.Never had any trouble with UI’s on Zebralight’s or any of the others.I like the light every thing else works fine,i won’t be locking it out with the switch anymore.
Lockout on Mankers are tough. It sounds easy: single click, double click, triple click… but timing is very crucial. First time I locked and unlocked my MK34 - it was like a week after I got the light - I felt like Indiana Jones who solved some 2000 year old puzzle to access the gold chamber or something.
I tried pretty much for two days my flashlight (OCD kicked in)!
I hear that’s how he did it…
