I have two subtank mini rba's and the one currently in use is doin okay 2days so far fine.Just to see how the other one hit(i forgot why I didn't use the build in tht one) I put it on the base..using mrgoodvape sundae funday...power it up nd do a vape....it's.got a metal like taste to it..unpleasant.it's running at 1.2 which isn't what I like.. .7-1 has been good for me..but the taste isn't good at all.I've been having some problems lately with either a funky taste,burnt or major juice spurts .takes me many coils till one works .the coil I'm using is .7and from when I put it in it never had tht metallic taste to it but the other one does...I'm sick of not knowing y these things happen and coming across as.completely stupid to all of you but I'm trying to learn about why things like this are happening to me.so,metallic taste,why? Burnt,could it be too little cotton? Too much? juice spurts,cotton problem? I'm Waiting on the cotton squares from slowtech and am using the cotton my local(and very close)vape shop uses..they all use the cotton so it's got to be me..can someone nicely help me..I'm just trying to learn.
