the dosage cups that we call D cups (after the K cup) are great for us. The 8 pack storage device is handy, glad we got the extra cups, going to a festival located in a hotel it was handy 
however storing that many cups better use a Boveda. Having only vaped at party’s or on occasion a coffee shop I can’t really compare it to any other devices, but compared to burning it’s very nice, the throat feels better though you can still get a big enough hit that you can’t help but to cough
I also think it’s a cleaner high, if that’s such a thing 
over all we’re very satisfied with our 21st century smoking device,
