This is how I feel . I ' ve been in a lot of monogamous relationships , which I now know doesn ' t work for me . Cheating has always been more of a boundarytrust issue than a jealousy thing for me . Now I know that I don ' t care if my partner sleeps with other people . I ' d rather them do that and be satisfied than not have their needs met and have them resent me for it or feel obligated to be someone I ' m not . And visa versa . <| sep |> Freedom Fried Corn Dog ! <| sep |> i never had the tfv 4 so i cant comment on it , a friend of mine used it religiously every day at work and loved it , till he got a tfv 8 which he loves right now . Ive only had problems with the TFV 8 leaking when ive left the top fill open , or accidentally knocked it open . other than that i would say its pretty solid , I do use only 7030 and higher generally max VG juice tho , I probably wouldnt use too much 5050 or lower mix in it . as for being a hog on coils , it deffinately can be , if you only vape high sweetener juices , it will gunk the coils really fast because it goes through so much juice . but I think you will find this problem with pretty much all sub ohm tanks with prefab coils it happens to my crown v 1 and herakles plus as well . I dont know how they would affect the ccells in vapeoresso ' s tanks never owned any of them but maybe utikifromwheatland could shed some light on em I do know ceramic coils last longer on average tho
