Traded analogs for a 4081 device(smokestik), about a week ago and loving it..It came with 3 prefilled cartomizers and I also bought a 5 pack of prefilled cartomizers..I am not a heavy smoker/vaper but these things wouldnt last half a day..After discovering this forum and realizing I could refill I just received my first order of e juice from backwoods brew today and I have 5 carts sitting on my desk soaking in juice..The stuff smells great cant wait to try it..After seeing what the carts are supposed to look like after I add the juice and the cart is full I popped the top of two "prefilled" carts and they looked bone dry..Is this normal? No wonder these things werent lasting me half a day..and I got the burnt taste with two of them....Now that I got plenty of juice I will keep them moist all the time..No more "prefilled" carts for me..juice all the way..
