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.
Absolute letdown; overpowered by the typical Up&Go flavour with no cookies.
Russ hoped it would taste like a Super Shake, but it just tasted like regular Up&Go. He got the cream and only a faint hint of Oreo, called it a letdown and rated it 3/10, which matches the on-screen graphic.
