WOW, I see what you mean, 2 days and nothing. . I am sorry for that.
I said I have posted a couple times on this board & none of my posts have been responded to. It wasn't just this one. There is another one that is 8 days old with no reply. No need to be snooty, I was just asking if I was doing something wrong to be ignored.
V4L actually has a good selection when it comes to 808 threaded accessories. But there are a few other companies that do make some things for the 808 but most companies just have regular carto's and nothing else. 808 threads are not the most popular threads which you are finding out

What kinda problems are you having? Are you using the dual coil carto's or the single coil for your tank?
Leaking issues. I've spoke to Morandir indepth about them. I found out AFTER I bought a ton of 808 carto tanks that I can't handle high strengths of PG. I can however do 50/50 mixes. My tanks are fine until I go outside & the temp rises or I'm in the car (we don't have AC, but I live in Western Washington, it's not THAT hot!) & the sun is shining on me while I vape, etc. The temp rises slightly, my tanks leak. However, I've noticed a lot of people on the V4L forum complaining about their cartos not lasting as long or getting more bum ones in their batches, etc, so I was curious if there was another type of 808 tank carto that would fit the tanks I have, but I take it from the answers I received from both of you that would be a no? So, my other question is, would a 510 carto fit in an 808 tank? Like are they the same diameter? I realize that I would have to buy an adapter to make it fit the battery. I just hate to have all these tanks that I can't use, so I thought I would give a different brand of cartomizers a shot before I gave up on them, if they exist. Morandir says that I'm going to have issues because carto tanks & 50/50 juices don't work well together, especially when the temp fluctuates.
The Phoenix bottom coil cartomizer IMHO are excellent both in flavor and throat hit. They are easy to clean, just soak in vodka or pga overnight and quick dry burn when they dry out. I have been using the 510 version but now they have 808 here

Thanks, I will keep those in mind! Do you know if they work with higher VG juices? I thought I read somewhere that the long wicks don't work well with high vg % juices....but I've read so much being a newbie that my head has spun a few times in the last few months.
