What's wrong with the simple silicone caps like in the KR808? No glue, no need for a needle. The extra long silicone mouthpiece can hold the other cap in place to prevent leaking (which it seems like it does anyway). Why complicate it more, or am I missing something?
I agree.. I made a video of it earlier in this thread... in fact I believe it was one of v1's suggestions that sparked me to try... that and I use cartomizer parts for just about every tip and trick ecig related
