The taste of Kitkat is pretty good. The flavour is also good, The chocolate covering is extra-ordinary. I would recommend it to others though. If you are calorie conscious, then in that case, It is not advisable to eat the product.
So, sometimes a white layer is formed which is annoying. So even they say it is safe to eat, I think otherwise.
Unless, They can try to correct it, My review’s gonna be negative
