Every number is Russ’s own rating out of 10. Russ has previously stated that he never scores in sponsored videos, so the food he reviews carries no applied pressure or bias.
This is a joke. This is fucked. (He objects to the spoon being removed, not to the taste.)
Russ isn't reviewing the taste here. He rants about Yogo removing the spoon from its Yogo Mix pack: less plastic, but the same price, and you have to eat it with your fingers. He also points out the rest of the pack is still fully plastic and says even the Popper switched to a paper straw. There is no numeric rating.
There you go, mix it up, and it's an absolute fucking treat.
Russ shows how to pop the M&M's minis into the Yogo and mix it, calls it an absolute treat, then has a quick scoop of 'the real stuff' before making the shot. No numeric score.
