This is what I use. I have no frame of reference, but it is very easy and convenient to use, so I can attest to that. It gets the job done, I enjoy it enough to prefer vaping with this over lighting it up. The taste is good. It has held up for 6 months thus far, and I haven't been particularly delicate with it. I'm really happy with the purchase.
Ff2 is the worst dryherb vape, it's on my shelf collecting dust, horrible draw, poor functionality, gets uncomfortably hot and has shit battery life. Worst of my vape purchases. I could recommend so many more over the ff2 Sent from my SM-N950U using Grasscity Forum mobile app
