I said i would post my opinion now i have one as it came today.
So far its been working perfectly, couldnt fault it at all. I surpose every one for each ecig is diffeent but the one for this DSE901 is great, no leaks. The good thing i like about using a tank as opposed to using cartridges etc; is that when i used to use carts and wasnt getting that much vapour or whatever i used to be in a puzzle to what the problem was. Was it the cartridges not being filled up enough, did i need to refill them? was the battery bust? did the atty need changing? etc; where as with this tank system you know that if your not getting enough vapour its either just the battery or in the most likely case the atty.
I like them so far
Cool man, so far the 901 tank system seems to work for those who have tried it. maybe ego-t users need to get an adapter and try the 901. lol
