I tried
these (the 2.4-2.6ohm version) on my minis (with a $2 510 to 808 adapter) and they work quite well. They look nicer on the minis than the X2 Clearos plus, they're $11 for a box of 5 so even with the extra cost of adapters, they're nice and cheap.
I use the CE3s on my Lavatube for trying out new juices as I have terrible luck with Attys and the CE3s are very easy to clean out. I still prefer SI carts for my minis though. They look great, vape great and since they aren't PT and a cart lasts almost exactly as long as a full charge I don't have a need for any kind of a tank system.
