There is no use of the word "burrs" in any of the written descriptions nor the spokesperson doing the demo of the grinder in the video. In fact, she specifically says 'blades' and makes a point to highlight the thing that sets this blade grinder apart ... the steel mesh screen that 'catches irregularly ground beans' so they don't end up in the ground receptacle.
She also states quite clearly that this blade grinder is unlike all the other blade grinders in that it's the only one that 'processes the beans once'.
It's clear that this is an overpriced blade grinder for drip coffee makers.
