Well, I don't know what I can say that I didn't cover in the video, but here goes.
Then Hendu SmokeStik is a very nice unit. Because it's silver and not painted, it is SLIGHTLY narrower than the standard SmokeStik battery. When you get these, you'll want the silver (no color label) carto for it.
The battery has a nice
jewel at the end instead of the standard ash simulated LED, and has a nice blue light behind it. The end is almost flush/flat as well. There is white lettering along the side of the battery telling the user what you are using, but isn't showy.
I've had the battery last 4 hours one day (at work) and the following day the whole (work) day. It was pretty busy the 2nd day, so because of that I wasn't hitting it as often I'm sure. Either way, for a 190mah battery, it lasts a good while. I have not sat and vaped one hard just to time it, so your milage may vary.
All in all, a good stylish unit. When I got it in the mail, I made the mistake of opening up the package in the presence of my wife, now I am down to one battery.
