The battery works well. I like the variable voltage. The look is great, very discreet and stylish.
It didn’t hold up very well, however. I used it for a week and when I tried to remove my cart, the connector on the inside of the battery came loose because a little concentrate leaked through the pin on the bottom of the cart and all the wires pulled out. I’ve tried to insert them back into the battery but, they don’t want to go back in properly, rendering the battery useless.
If the battery were constructed a little more sturdily, this thing would be a home run. Until the connector is seared into the bottom of the battery a little better, I don’t see how I can use it for concentrates.
I regret to hear that you have received a defective unit.
I will create a ticket for you regarding this issue.
