Ha les017 and tdwave i had to clean one of the two carts that i started wih on day one.the one i had to clean was the lr one the reg is still going strong with no sign of letting up yet.both had the same juice 70%pg@30%vg it is a tropical punch from viking vapor.not bad for 3 weeks i can deal with that well let them dry now and see if i can get 3 more weeks out of them.then drew was getting to tight on the lr cart and the taste was also dulled a lot.
