It's vile.
Sorry to be the bearer of bad news.
I tried it a couple of months ago, but didn't even finish the mini bar.
The choc was bland, the stevia bitter, and the whole thing was claggy.
That doesn't mean you won't like it, but just in case, don't save it for a special occasion.
If you love it, buy some more for Xmas.
If you don't, you won't be disappointed on the day.
(I am a self confessed choccy snob, so take my opinion with hint of a pinch of sea salt and chilli flavoured single estate 70% cocoa solid
)
