The Vanilla Plenny bar is a filling option, although the taste is very subtle - it feels suitable as a 'blank canvas' of a meal. I've tried some of the other flavours but the flavours I tried weren't suited to my personal tastes - I think I'd personally prefer flavours that were sweeter and more flavourful, although this likely would only be achievable using artificial flavourings which seems to go against the ethos of the product. Overall a good option. If they had stronger and sweeter flavours I'd be enthusiastic to try them. I wish there was an option to pay a little more for a single-bar 'sample pack' to figure out which bars I liked and which I didn't - the Flavour Mix box gives you two of each bar, which feels a little wasteful for flavours you don't find you like. Customer service is a 10/10 though, Jimmy Joy had a phenomenal response when I emailed.
