I just purchased an Ovale v6 vv system, that came with two clearomizers. The pv itself works fantastic, I filled the clearomizer up with juice and it vaped wonderfully. The problem I have is that once the clearomizer ran dry and I refilled it, for whatever it reason, it will not hit like it did when it was first filled. The hit becomes dry with very low vapor production and taste. I can't seem to get a pic of the clearomizer to upload but it's about an inch and a half tall and is filled with a cotton filler. I know the device is okay because when the first clearomizer acted up and I filled the second one, it hit great until I refilled it and had the same problem... Essentially my question is, what other clearomizers or tanks will fit on the ovale v6? I just bought this a day ago and I don't even want t buy any more of these clearomizer if they're going to behave this way.. I've seen a few people on YouTube using something called a "boge" tank on it (sp?).. Which he seemed to have no problem with.. I guess I just need something that will handle that recessed connection and not leak, work after refilling, etc. lol I've smoked a kr808-d for over a year now and it works great for me.. This is the first time I ventured outside of that and this clearomizer that came with it, just stinks, what good if you can't refill right? Thank you ECF!!!
