I've tried a lot of the solubarome one shots and they were all OK (apart from reactor pluid), none really tasted much like the original juice they were trying to copy though.
The reactor pluid one was most disappointing, I mixed it up and gave it a bit of a speed steep, filled my tank and tried it...All I could taste was lime, it was quite nice but next time I went back to it I noticed it had seperated in the tank and had little blobs of oil type stuff floating around.
The stuff in the bottle had totally seperated, the green liquid on the bottom with a thick layer of oil on top...Not something I want to be vaping so I binned it.
So, I'd recommend putting a few drops of any solubarome concentrates in a glass of water or something to test for oil before mixing.
