I love the discreet compact nature of this battery, but I didn’t anticipate the lid giving so little clearance. Pre filled 1g cartridges are too tall, and the lid can’t shut. Other than that, it’s fantastic.
I love that the cartridge sits inside as I have a tendency to drop things. I also like that it has 4 settings to use to make it a stronger pull or a softer pull.

Great product, would highly recommend it.
