I quit buying carts until I tried this V Mod square battery. I've had many pen style batteries snap and break in my pockets (& I never carry purses) , so this unit is perfect for me. The cart magnet keeps it secure and it's easier to charge than using those USB screw on types for pen batteries. 4 stars for now due to it's older mini android input for charging but if they redesign it with a USB - C input it'll be 5 stars.
