Review of Blue Ice Flavor-FW:

tested at 10%. supposed to be a blue razberry slushy but its pretty far off. forward i taste a slightly chalky koolada with just a bit of menthol-mint flavor but the chalkyness goes away after 2 days, or in a mix. the cooling flavor and feel is definately dominant and at 10% its pretty cold like breathing in extream snowy weather - but you could certainly take it up to 15% if you really like menthol-like flavors. hard to say how much to use in a mix as 1% would be noticeable. up towards 7% it would start to take over a mix. now on to the blue raspberry flavor-though the flavor is secondary its very pleasant and not mediciney. it is on the sweet side but could certainly use sweetener and it only has just the slightest sour-tang (though almost unnoticeable). i do not get and chemical or off notes from this concentrate. i would highly suggest this flavor for a sweet blue razberry koolada flavor!
