Been on a citrus vibe for quite a while and tend to use Favour Art for their concentrates. I have seen these around for a while now and thought I would give em a try. Off the bat it's a pretty good flavour and on par with FA original. I tend to use it in Key Lime and chewy sweet recipes etc.I don't think there are many reviews from top mixers who give a pretty good description of the concentrates and best percentage to mix, but lime is a strong flavour in general, go easy and work up! It works for me and I am grateful to Rainbow vapes for stocking it and delivering quickly for my citrus fix!!!
