A 4 in one top cap would be the best, i'm very interested 
Giulio,
I do the same oring thing as you with my Ego/Riva batts by placing the o ring over the threads and it seats down on the flat part of the Batt then I put on my Atty and screw the cone down snugg in the oring, since I use a drip tip and drip with them, then none of the liquid leaks out and even pulls back into the LR510 I use with them, your cone and oring is a nice mod on your GGTB.
I would like to see a 4 in one top cap myself on GGTB, we could always use an adapter with that 4 in 1 top cap if need be, why make all different caps if we don't need them, am I missing something, I think the 4-1 would be nice and sufficient, please let me know what others think here with this feature
GG ECIGS AUSTRALIA - GGTB
Seven still available, shipping a pain to the USA though sorry will vary between $2.50 and $27 to the USA.
Damn, have most things in stock, go for it guys
GGTS in stock too... maybe an 18650 x 2 while you're there?
Slim with extension? Both engraved.
Clear AVS tanks Monday... 40 AVS tanks in stock and I'm an actual user who can help and advise you.
SorryI still owe u a bit, what can fit in an envelope? O-rings?
I'd be willing to bet a lot of customers in the Uk would be more interested in a native 510 connector than 901.
As I said earlier in the thread I've got in the order of 20 510 connector atomisers/cartomisers for each 901 I own.
thanks Jumi.
How are you doing? I would phone you or drinking a coffee with you but better contact via forum lol
The switch seems to have a nice short push. Very well made unit. Not so well made pictures.
