Unsure why some people are saying the pods only last a day. They must vape a lot. I’ve had my epen 3 for 2 weeks now and i’m only on my 2nd pod. I use it several times a day when the craving hits & so far have stayed off the cigarettes. I also like the design as you can carry it in a pocket/bag without worrying it will spill, which i’ve Had issues with before with tanks. Fantastic product.
