Absolutely LOVE This Thing!!

Absolutely amazing mod battery. Honestly the best that I have ever used. I admit fully that I do not buy all of my vape carts from B&F because they are often sold out of the shimmer cartridges that I like so I needed a decent battery with variable voltage. I've used (and broken) 2 Vessel pens, which I would never purchase again. This battery had none of the issues that any of the other variable voltage pens have. I love the magnet connection, because if you drop it, the cart just pops out instead of breaking. The voltage is variable by 0.1v increments, which gives a perfectly tailored experience not only for each cart, but even the situation (sometimes I like a cloud, sometimes just a little bit of cooler smoke). The slider switch is a little stiff, but I almost fell like it has to be to stay at one of the notches without falling inside the case, and it really doesn't need to be changed often (unless you're changing carts every few puffs and they are all different brands...). The Battery life is incredible as well. I use it pretty heavily on a daily basis and it last longer than any other battery I've ever had. There are some elements that really don't make a lot of sese, but they are more cosmetic than others. For example, the back window that allows you to see how much is left in the cart without removing the cartridge? Unless it's at the bottom notch of the slider, it really doesn't work because it's full of the magnetic plug instead of the cartridge. You also can't really see into it without the light on, which only activates when you start heating the cart. These really don't make a significant difference though and it is still, by far, the best pen I've ever had.

It works as advertised but we've had some issues

Been using for the past 2 weeks now and have formulated enough of an opinion. What I liked was the variable voltage aspect and the fact that it's quite universal in the cartridge world. The overall build of the battery box isn't that bad but there is room for improvement. I got it in white and it's like a pearl-satin finish with silver accents. Display is nice. Off message is "Take care" which is cute lol. The battery has been pretty good over these past 2 weeks, I'm at half the bars right now. I use it around 2-3 times a day and not really long sessions. The cons: There is a cartridge slider on the side that is always giving me grief, it's so hard to maneuver up to the point of thumb soreness. For that reason I knocked off one star. I had another issue where I ******* on cartridge maybe a bit too tightly and when I tried to use it, the display kept reading "shorted". I had to go to dr.google and reddit to help solve my problem. All it took was some untightening for it to work again. I'll be honest and say I'm not super in love as it gave me a few too many hiccups than expected. However it still works and I hope it lasts for a while considering the price. Hopefully my slider is just faulty because other than that I'd say to try it out to see if it suits your vaping needs. I'll still be using mine.
