Ok so I have a mom and pops mini sub tank and I am wondering is the notcigs m1a1 tank any better looking to order one more tank. I like the mom and pops tank. I guess what I am looking for is can I use the Iken Vape Fusions on either tank or will the just work with the notcigs tank? I love the fusions and that will be the deal breaker for me I just have been using the Carto that came with the mom and pops tank so I have tried to put a Fusion in there yet. Im hoping it will fit. Thanks for any help....
