Used the burpple 3 for 3 promo and tried 3 flavours -

Lychee Raspberry: My favourite out of the 3, 9/10!!! Nice balance of flavours yum rlly recommend!!
Yuzu Lemon: Yuzu and lemon/sour taste is nice, 8/10
Durian: durian taste present but not as much of the cheesecake, an OK durian-flavoured cake, 7/10

Recommend trying if you have the promo! :-)
