I bought an M401 after I got this from a friend at work. The carts for the 401 are not as long or as big around as this one so I can't use the carts for both.
I posted before trying to figure out what this is. The batery screws into the atomizer as you can see in the photo and the cart just slides over the atomizer.
I am wondering if the Janty kissbox or DSE 103 carts might work because it looks like they are just slightly bigger around and longer than the M401. The diameter of the 401 is just barely to small to fit this. The length of the cart is about 38mm the 401 is only 35mm. Diameter or 401 is 9mm the unknown is about 9.5mm if that helps.
