The filling of this egg is just like Cad Creme Egg, just as sweet. I wasn't keen on the chocolate on its own, but having enough of the filling at the same time makes the chocolate sweeter and nicer. A thinner, sweeter chocolate shell would be better, hence four stars, but it is so close to a Creme Egg apart from that, I would give 4.5 stars if I could.
I really like Mummy Meagz Gems, as they taste really close to smarties, and the sweet shells make the chocolate taste sweeter and nicer.
