[Review] Manker E05 Copper Edition

Question, is the 3C bugged, or is it working fine.
My manker U22 III, If I 3-click (to strobe), half the time it's goes to the "General mode", and other half time it goes to the "Special mode", and it remembers the last time, and always go to the other mode.

I was thinking of buying it for present, but the question remains is it also bugged (or by design, I don't know why it's doing that on my manker U22 III)
