I find it hard to bash something you've not even tried. I try to read other's reviews and be as subjective as I can about suggestions and opinions.
I had to bust my .... and do a lot of things my wife and Dr's are still mad about for me to be able to come up with the money to buy a Provari. I assure you, it was no easy thing for me to come up with this much free money!
I also have a Lava tube, as soon as I got it I knew it wouldn't last long in my world! The chrome was flaking off on the way home, the thread connections are loose as a goose and every time I dropped it I would cringe knowing that would be the last time it worked! The battery threads are loose and I fear just the spring pressure alone will strip them out. It's built like junk, plain and simple! Does it vape any different than the Provari? Not really, but there's no way it would have lasted in my world more than a few months.
Around 2009 I bought a BB from Altsmoke, I forget now how much it cost then, but it was a chunk to come up with! People didn't get the price for that then either, but it still works! I actually used it when I would be working in the yard and garage before I got the Provari because I knew the Lava tube wouldn't hold up to the abuse.
I bought the Provari because it will take the abuse I will give it. The build quality and materials are excellent, as a machinist for 13yrs I'm a pretty good judge on these things. I don't fear dropping it, the connection is tight, the battery cap doesn't feel like it's ready to pop out, there is no comparison between the two!
It doesn't make everything wonderful and peachy, it doesn't make my juice taste better, but it works, and I know it will keep working! Is it for everybody, nope! But I don't want an IHybrid or a Zenisis either, but I see why some do. I don't say they are stupid or crazy for spending that kind of money on them. Different strokes for different folks. If you don't want one, don't think you need one, fine, enjoy what you have or want. But this works for me, I had my reasons for making that choice and I'm glad I did. So please don't call it a scamor a ripoff until you have a better understanding of the reasons people made the choices they did.
