I've never had a sample of that particular kit, but I've tried alot of others. My best friend loves those kits, so I've tried a number of them.
If you like wine coolers, you'll love those kits. Very fruity, and low ABV, so they don't take long at all to make. My friend makes the mango something, and I gave her the kiwi something as a wedding present. These are fine as a wine cooler type beverage, and she loves them. I drank a few of them this past summer at her pool parties, and they tasted great. I'm more of a "dinner wine" kind of person, though, and wouldn't make one for myself.
If you like wine cooler type drinks, or your friends do, an Island Mist kit would be perfect for you.
