Lurking, the battery is great. I used it for 3-4 bowls yesterday and it still shows full charge. This battery, which costs $60 to replace, is guaranteed for a year. I'm willing to pay that per year. And if you install the app on your phone, they replace the two year warranty with a five year warranty. So if this thing lasts for 5 years, I will be very happy.
This is why I got rid of the Haze vaporizer I had a couple of years ago: batteries needed frequent charging and frequent replacement. Then I decided fk the portable vaporizers: the batteries suck, and I went with a Plenty by Storz & Bickel. It's a nice plug-in vape, but it's slow to heat up (for the impatient vaper), and it's slow to cool down. It just doesn't have the kick that the MV1 does, which is only hot when you push the button and inhale.
I am really impressed with the MV1 vape experience, which feels more like a concentrate. And that's from a couple of bowls, each holding approximately .1 gm of bud. Yes: I said 1/10th of a gram. Hot damn!!! I know I should have saved the money for my old age, but fk that...
