Joe, try a thicker O ring at the head, it may help.

My Brass CooYoo just arrived today and sadly it doesn't work I've tried multiple charged 10180 batteries and nothing gets even the faintest output. The usb charger led comes on when I plug the body in but that's the only sign of life in it.
I don't suppose anyone has any ideas on things to try to bring it to life?
Time to find out what GearBest's customer service is like!
I receive mine just the other day and having the exact same issue with the twist flickering.Received my SS version today. Much smaller than I was expecting (much shorter than my LED Lenser K2), and a nice neutral(ish) tint.
The only "issue" is that during the twist, there is a long period of flickering low mode light before it reaches a point where the light is constant. Is this normal? (I've not owned a twisty before).
Thanks, I tried that. It has reduced the flickering but hasn't eliminated it.Not normal. It may be that the contacts are a bit grubby. Give the ends of your cell a good rub against something to clean off any tarnish and try again.
Does it flicker from off to low or from low to high. ie: does it get brighter when flickering or darker ?
Oh, and did you also clean the contacts above the charge port? The brass 'nub'.
Last off, I found on one of mine that some bits were caught in the head under the flexible hi/low plate. A blast of air cleaned that out.
