I got mine either 2 or 3 weeks ago. So far, I really like it, although I, too, am one who has no other experience with VV units to compare. Mine also came from Discount Vapers with the prefilled Tidy 10 Clearomizers. I didn't like the smell of the liquid that came in them so I emptied them out and filled them with my favorite liquid. The clearomizers aren't terrible, but they do have a rather hard draw to them which isn't too bad for me as I used light analogs which also had a sort of hard draw to them. I think I've figured out how to deal with the leaking problems, at both ends. I remove it from the battery to refill it. I make sure to have the syringe filled and ready before removing the little "stopper." It seems to act like a straw in that once the stopper is out it will leak but pretty much stops that once the stopper is back in place. After I fill it I wipe the bottom where it screws into the battery with a paper towel and twist a corner of the paper towel and insert it into the hole to mop up any liquid that might be in there. I also try to keep the unit standing upright (I use a very small, narrow glass to hold it since it has a tendency to fall over easily). I have also found that if I make certain there is a small gap, even a millimeter seems to work, between the stopper and the other little plastic thing (sorry for not knowing the correct terms for these things) with the hole to fill it. A small gap seems to prevent the liquid from getting in my mouth.
When the clearomizers work well they are great! Vapor production is good and the taste is wonderful. I don't even mind that they don't hold much liquid (only 1 ml) since I'm female and carry a purse so it's not a problem to carry around a bottle of liquid and my syringe. I like that there's no batting, and I can easily see how much liquid to put in it. They do, however, seem to get "stopped up" rather quickly. Both vapor production and flavor get reduced, although I've found I can effectively "refresh" them by dropping them into a cup of boiling water for around ten minutes (I remove both the plastic stoppers first). Still, I'd like to find something better, especially if I could find something that would still allow me to put the cap on. I clip the capped unit to my jeans' pocket to take with me when I go walking so it would be nice to find something that would still let me do that. I'm open to any suggestions if anyone has some.
