My wife and I found the M401 with pre-loaded vanilla cartridges to be smooth, consistent and very tasty. Not much throat hit. Looks like my failing eyesight will make refills nearly impossible 
But all in all I can see why the forum always says your choice in type of ecigs is a matter of personal preference. I just might give up my insistence on strong throat hit and buy pre-loaded M401 cartridges.
So where would I find the cheapest pre-loaded flavored cartridges for the M401? I'd prefer them to be individually sealed.
TIA,
Dave W.
