Mine have turned up today, reading the thread there were some complaints about bottles and labels. All are in child proof bottles with proper labels and with stickers saying what the nic levels are.
I can give a first impression based on tasting them on my finger, have been doing this for years. Rhubarb and custard is heavy on the custard, quite sweet, will need steeping but won't be unpleasant right away. Raspberry ripple is very nice, tastes exactly as it says on the tin, may have a sneaky tank full in a bit. Pink lemonade is very tart and heavy on the lemon, will need steeping. Peaches and cream is very peach heavy, cream is just an undertone, will need steeping.
