Hey dude! Thanks. I'm still using the Kanger Protank 2 with an airflow control valve, and either my Innokin iTaste VTR at home or my Innokin SVD 2.0 when I'm on the road. Both are totally obsolete now, but they still work just fine for me! My VTR is literally almost five years old, too... I got it in January 2014. It still works great, though, and I use it every single day; it's an indestructible 13-ounce block of steel! And I am down to 12 mg now!
