I tried something a little different this morning with my leo. I took a brand new cart and pricked the polyester several times with a needle. This seems to have helped quite a bit. Now, the atomizer leaks into the battery. Since my batteries are both sealed, it's not a big deal, just have to wipe it occassionally. It does seem to leak worse than my 801 ever did. Sure would be nice to get an atty that wicks good and does not leak for the leo. Are you listening Boge? I also ordered two more attys from MadVapes to have some back ups. I do not want to give up on the leo, but ........ I have not tried the fluval filling as yet, but am going to give it a try. Maybe I poked the polyester a little to much. I didn't count, lol, just poked it several times. Hope this helps a few folks. Has anyone else experienced a "leaking leo"? The two attys I recieved with my leo kits are both "gold". The two I ordered say they are "black gold". Anyone know if there's a difference? rsmith76
