I tried Feastables and here is my quick reaction as a fan of chocolate

Dark chocolate

It’s actually pretty good for a dark chocolate. Has the rich soulful flavour with the right amount of bitterness and sweetness. May not be better than Lindt but its a cheaper alternative if you want to try dark chocolate.

Milk chocolate

It def has the crunch but the taste is quite mid honestly. For the price of $3 Cad and its equivalent, I say its not worth it. Go buy 3 $1 milk chocolate bar with different brand and your money will be well worth it.

TLDR

Dark chocolate is good and a good cheaper alternative but milk chocolate is mid and rather buy a different chocolate brand like kit kat or Aeros
