I spent years looking for the perfect grinder. I see this and think, oh it looks like a great idea. Man, look, that thing sucks. My material was stuck in the bottom "grooves" 100% of the time. Every grind, I would have to poke it though. And it did a ****** job and actually grinding. I called the manufacturer because I thought surely, there is something wrong with mine. They asked for picks and a video of the grinding. They could clearly see it was stuck and wasn't shredding anything . They said it's not a manufacturing defect, it was functioning as designed. The issue was my material was "too wet". Seriously, I did this again with some ****** dry brick material. Man, it was simply too much stress for a grinder. I bought a SLX and could be happier. It's been over a year now.
