-1 star_ doesn't say type of cartridge. we do not know what to buy replacements with.
-1 star _I dont know this works properly.
plugged it up we will see with full charge.
I'd doesn't move up and down
it does vibrate tho like a tattoo gun but as far as the bano cartridges moving up and down on skin like micro dermal pen I can not say this is same appears it would scratch your skin just vibrating and video shows cartridges moving in slow mom up and down
feels like a tattoo gun and it only adjusts from 0 to 2.5 like halfway around the circle instead of turning all way around twice but that might be normal I'm not sure dermapen go up to 3. something I thought?
going to record video and put it in slow motion to see and I
will update later
