I use the same Vape. Yes, yours is not working correctly---but you must follow their instructions exactly!
I LOVE the "NG" Vape.
But, buy them at "gotvape.com" Because, you'll get a free Lifetime Warranty and free shipping! I have sent mine back twice, got replacement each time, at NO cost!
"gotvape.com" Rocks--and I have NO connection with them. They are just the least expensive & very cool!
