As good as Ikenvape has been about designing attys-801 stealth, cannon, i06 why not design and make an i06 with the sleeve buit onto it? I mean the cannon is basically an 801 mini with a 510 connector, right? So anyone intersted in an i06 with built on sleeve? It would stop all the complaints of the atty sleeve getting stuck in the drip tips (and you could use any 510 or 901 drip tip). I have had this happen a few times even as careful as I am with them. By the way the i06 is about all I use anymore.
