Review of Arnott's Tim Tam Chocolate Biscuits Original 200g

This is our family favorite Chocolate biscuit and we only like the original flavor. My sister in law always buy a few packets of Tim Tam to take back home when she visited Australia. It is not too sweet compare to other Chocolate biscuit. The Chocolate coating can easily be melted in Summer so it doesn't taste as good when the coating melt. However if we put it in the fridge then the coating become hard also not great to eat. We usually avoid buying it in hot summer.
