CoffeeWorm - Looks like a negative name to me. It could mean enthusiast as well but with food product, it doesn't give the right meaning. xx probably in reseller market.
Wikzik - Confusing. I wouldn't qualify it as a brandable. It could be v or a w. Still confusing. xx is what I would say. Although, this may have possibility of selling, I'd say go for better names in brandable niche.
