I tried the Patriot raspberry 30mg juice a few weeks ago & liked it a lot, apart from needing more strength of flavour, so I ordered two 10ml bottles of red label concentrate, assuming that the flavour would be similar & I could mix a strong batch.
WRONG!
To try it, I put 3 drops into my 3.5ml DCT tank & I certainly could taste it then! Trouble is, it's ALL I could taste & smell for hours after.
The flavour/smell is so sickly & unpleasant I literally feel nauseous if I catch the slightest whiff of it now. I had to tip away the contents of the nearly full tank & hoped that ordinary tobacco flavour would wash out the carto. It didn't, & after a couple of hours of trying to wash it through, I ended up pouring about 5mls of PG straight through it to wash out what I can only describe as the taste of cheap synthetic cake flavouring.
Sorry guys, this one is truly horrible & I guess I'm stuck with 20mls of the stuff?
I don't even dare put it down the sink in case the kitchen is permanently tainted.

To be honest, I'm a pretty disappointed with the promised flavours so far, apart from American Red tobacco. Everything else has been average to poor.
No chance of an exchange on the Raspberry, is there?
