When first started out, I used a lavatube....but honestly for the price, you can do a lot better including their tanks. It was a decent atomizer back in the day...but not compared to what you can get for the $, unless somebody sells to you dirt cheap.
Even comparing to my MVP 2.0, even though it tops out at 11 watts, the vape is smoother than the lava tube....I won't go into the technical details on why.. but for the price you can do a lot better, like MVP 2.0, or the new Innokin SVD 2.0 coming out.
On tanks, stick with Kanger aerotank mini or Nautilus Mini with Nautilus BVC coils...
