That's probably because it doesn't use the Trespade burrs.
Here's the Trespade:
Here's the Isomac
Notice that it has almost no twist, and six not five coarse channels. Moreover, it is made of polished base metal, not carbon steel, the motor is underpowered, and the burrs are poorly defined. In other words, it's a piece of junk.
The Baratza and Capresso are far better grinders than the Isomac. But, repeating the sales copy of the manufacturers themselves, for about the 500th time, not designed for commercial groups.
