just to put my

in... just because lol... I'm fairly new to vaping (about a month and a half in) and I have definitely bought a lot of cheap 'junk'... but when I think about it, it hasn't been CHEAP and it hasn't been JUNK. I still use my old V2 battery & cartos (along side my 2 Sigelei's which are FAR from JUNK) from time to time, and my ego batteries and my itaste VV V3 (also not junk) and my ksmart. I bought 2 protank mini 2's because everyone said they were great and guess what, I can't even use them (just sold them actually), but not because they were junk, but because I kept getting dry hits, it just so happens that carto tanks are better FOR ME, I still hear about TONS of people who love their protanks.
I didn't switch because of money, I switched because of my health and my kids. I could have gotten a Provari at any time and I choose not to, I don't want one (and sorry, but I don't understand why people who own them are so unkind to people who don't!). I may not get a lifetime of use out of my Sigelei's, but they've both already paid for themselves. I took SMALL babysteps up to my mods and I truly believe if I would have jumped to them too soon, I wouldn't be vaping still. I had a VV/VW device too soon and ended up taking it back because it was way more than I needed at the time.
None of that even matters, what matters is how inappropriate it is to judge people who don't do as you do! Everyone is unique and have their own personal way of doing things and there is NOTHING wrong with that. I do not regret one thing I've bought, it's about the journey, not the destination!
