The Grinta is on par with Rocky & MDF grinders, not really intended for serious use. It's too bad whoever bought it didn't check its specs or read the right reviews.
I was hoping that your trip to the garbage can would involve a slip and the Grinta would be history. Suggest to your employers that they can sell the Grinta on CL and make enough to buy a much better grinder - Cunnil Tranquilo at $238.
