I own a Baby priv that I no longer use, three Mag 225w, 4 Prince TFV12 tanks with another one on the way.

Sounds like bad luck man... My Majesty Luxe seems to be doing fine, bought it in may. I'm even certain that the chip in it is better than in Steam Crave Hadron or Eleaf Pico Squeeze 2, at least where safety is concernedI have THREE Broken ones. Didn't even last three months. SMOK Mods are cheap junk.
If you are satisfied with what you have then you are much farther ahead of the game than most of us. Personally I think the X is better, but a stopgap upgrade. Smok loves to make tons of products for no apparent reason. But I have yet to find one I did not like for one reason or another.
I don’t work for the competition. I really like the smok mods I was using. I still use my smok tanks but the mods are too fragile and break very easily. I have a geek vape aegis now and it is built much stronger.I have no problems, and I'm quite satisfied with my NOVO 2 {Is the Novo X any better?} - I bought 2 extra Novo 2 as back-ups and haven't yet had the need to open the packages,
Sometimes I wonder if the anti-Smok posters are working for competing companies ???
