Great

I've been looking for decent cig-style 510 batteries for a while and these are the best I found. They also look super dope (no pun intended.) I actually use these with old style 510 attys to vape regular tobacco and they are perfect. Also, shipping was incredibly fast and they even included some excellent free stickers! Vape on, folks. Love it and will definitely be back for other products.

Nice to have in the pocket. Easy to be stealth when I’m not looking for the button when I’m trying to be sneaky. Go at least three seconds

Sometimes it just won't hit. Each strain seems to be affected differently (could have to do with burn temps) but it is inconsistent at best. Doesn't matter if it's fully charged. Cannot recommend.
