I've a few cider kits including the bulldog strawberry and kiwi, but IMO the ones I've made from apple juice cartons and Lowicz syrups for priming and flavouring have come out miles better, and don't really take much more effort than the kits and work out either the same price or slightly cheaper.. worth thinking about for sure !
I've not yet made a cider kit that's been that good, made a few 'On the Rocks' brand ones too, which are ok'ish
