super concentrate

I'd like to know from anyone who has made more than one purchase SC Parlay over an extended period if they have noticed a marked inconsistency in flavor at any time. I bought a 10ml bottle in late 2018 and liked it, but used other flavors more. I revisited it the week before last when I saw it...

Those alcohol-based flavorings from the Chinese brand SC, not the Real Flavor SC line. I was looking through BullCity, and SC 10mLs are $3.99 with practically no reviews. They're also barely used on E-liquid Calculator. What's the deal with these flavors? Are they from a company called Vaping...
