Used my friend's when we were tailgating and I had to have it. So glad I bought it, I use this all the time. Perfect hits, great for passing around with friends, and discreet.
Pretty much exactly what you want in vape pen. Works on dry herbs and concentrate and lasts a long time before needing to recharge.
There's a reason this is one of the most popular pens around, because it's the best. Works just as well for flower as for concentrate. If you don't have one yet, get it ASAP. You won't regret it.
If you want big clouds of vapor from flower or concentrate, get this pen. I haven't had a single complaint.
