Rachus, great shots of the eGo-T and Go-go. The Go-go is like a cigar in size!
tdwave, maybe only the ones on this thread are using it and there will always be supplies for us
Here's my cartomizer method, although I may not be doing it the best. With the regular cartomizers I can notice when the flavor starts to taste a little off. Maybe a kind of drier taste. It's not precise, but that's how I do it. In general, with the regular carts I get anywhere from 10 to 30 refills. (Empty ones take around 25 drops, refills around 15) Every now and then I'll get a brand new one that doesn't produce the right amount of smoke from the beginning. It will go in the trash. I have never tried to work on one. So, with cartomizers, my biggest expense is the eliquids. This is one of the advantages of using cartomizers, your expense is pretty low. With regular carts I use about one box of 5 per month ($7.95 CigEasy).
The Go-go is a little different. On my very first fill (I ordered blank Go-carts) I put too much in. I was watching the fiber inside it as I filled because that's the way in the regulars. I was watching the fiber to stop when it suddenly gets like it won't take any more, but I overfilled! With the Go-cart, I have found that you have to watch the bottom. When a drop comes out of the bottom, it is full. On an empty one it looks like 90-93 drops and you are done. Also, after that drop appears, you will have to use a paper towel or similar and dob up the few little drops still on the bottom. It is pretty fast. That is the extent of the work with a Go-go and I am thrilled!
I have been using only the Go-go now for 2 weeks and it is awesome. I just switched to my second Go-cart yesterday because on the first one I didn't refill it on purpose to see what the effect is from too many drags and no refills. It acted just like the regular carts, it starts getting a very slight, but noticeable burnt taste. So the trick with the Go-go is knowing when to refill before running it dry. I've been refilling once a day and the refill ranges from 35-50 drops. So at that rate, it would take me 10 weeks to go through a box of 5 Go-carts. But I know they will exceed that from my previous experience with cartomizers!
