It’s my favorite too - especially when chilled for several hours. Just sweet enough without being bland, very smooth and the flavor is not overwhelming or too “artificial”. It’s definitely a winner.
A lot of people seem pretty down on chocolate but it’s grown on me. The only thing- and this is a huge caveat - is you need to blend it and put it in the fridge for a few hours. It helps to even out the flavor considerably and gets rid of the clumps. If I use the shaker and drink at room temperature it’s not as good.
