For the original price of 30 bucks you could have bought a mm that was way more accurate. The new price is more realistic but still high for what it is. If they added a volt tester it would make more sense. Then it would do all the electrical work needed to vape. You still need to buy a multimeter or volt tester to cover the bases.


also FYI you could have bought a ohms board, battery box, and 510 connector for much less money (if you was going to rebuild it anyway).
