“This stick pen is my favorite! It has a wide voltage range and at the lowest setting doesn’t burn my cartridges. I own 3 of them and plan on getting more!! Shipping was faster than expected as well!!”
“I generally buy 510's with a relatively thick oil and I've found that higher voltage provides superior performance. The 4v setting provides "I'll talk to you later" hits...very nice.”
“I love the battery. It’s fits perfect in my pockets, I can take it anywhere. And I love that I can change the temperature at the bottom to the voltage I want.”
