I have been testing flavors to find a good all day vape. I got the tabacco sampler cartos and really liked the "555" and "RY4" so I ordered a 30ml bottle of each. The "555" is great but the RY4 has a kind of alcohol taste and an acidic smell. I used brand new blank coolcarts and tried new blank wow cart too. Any ideas why the change. Says it was produced on 05-25-2010. The sampler was a standard cart but I wouldn't think it would make that muck difference.
