Query: protein bars

I bought two boxes of these bars lemon and raspberry and did not like either of them. I read reviews before buying but they were mixed so I went ahead and got them. Very disappointing. Both flavours tasted of chemicals and I doubt if either bar had even been near the flavour they were meant to be.Thought they would be a good snack to throw in my bag but no.I will never buy these again Yuck !
