I have been using my 601 for a fortnight now and I am still struggling to get a decent taste from it. I have changed e-liquids about 9 or 10 times, used the 3 different cartridges it came with (although I did remove the tobacco juice first), tried the straw mod in the cartridge, used them with the cartridge filled to slushy-ness, half filled, dripped in to atty with no cartridge at all. I have used Menthols, Raspberry, Apple, Arctic Ice, Coffee, single and double flavoured juices to no avail. I have used a100%PG, 80%PG-20%VG and 50/50. The vapour is very cool but plentiful in most instances. The batteries are fully charged. I have blown through the battery section to make sure there is no lingering juice or condensation. I've tried covering the air intake a little to concentrate the vapour with no (or very minute) discernible change. To be honest it works like a charm with the exception of flavour. It all tastes like straight PG with the the slightest of flavouring, but not enough to identify what it is. Any ideas on fixing my little problem.
