"recent tests of the production model (seen in three videos I’ve watched) aren’t entirely convincing. It doesn’t appear to have the cleaning power of the Degritter..."
I'm wary of the price-"ya get what you pay for"
Perhaps a little more time to figure out getting a more powerful process and keep price low-then time to jump on it.
The idea appears solid. The DIY's are too DIY. Someone will figure out how to refine it hopefully.
