“I have use there cartridges for a long time! I find they are the closest to a real cigarette.
The only issue is the bad cartridges, ones that release the liquid when you smoke it and I have had on occasion new cartridges that will not work at all.
There would be a way to return the defective cartridges and receive credit.
I am 68 and live on a fixed income & they are not cheap.
Sincerely,”
