I own 2 Liguinators and here is an abridged version of my experience with them.
I first got a 3ml tank and some extra pre-cut cartos. Very slidey but no leaks from the tank at all. The carto however went into siphon mode about 30 minutes in. I am very experienced with cartos and realized that the issue could not be the tank itself as the tank was NOT leaking. So I took another carto (also from vaporescence) and 2 hours later it started siphoning. Same result over and over till I had cycled through all of the cartos.
I contacted vaporescence and they replied promptly and asked me to send them the tank and they will take care of the issue. Well...the tank is not the issue but I appreciated their offer. I even ordered aan 8ml BFT from them as they assured me that the new tanks were not slidey at all.
And they are correct. The new tanks fit the carto properly. Problem is that every XL DC carto they sent with the new BFT did the same thing that happened with the cartos they supplied with the 3ml tanks.
They all turned into siphons over various lengths of time. Some instantly and some longer but none lasted more than 3 hours.
Time to fix this....
I also own a competitors tank and had some of their pre-cut cartos on hand. I stuck them in my original 3ml tanks and voila'! problem solved. For the BFT I punched a couple of stainless DC's I had and no leaks there either.
Obviously whoever is cutting their cartos is the one messing up and should be much more careful and consistent in their work.
Conclusion: I would buy this product again...but only if they do NOT include the carto and drip tip and drop the price accordingly.
Just one guys opinion...YMMV!
