This replaced a craftsman unit that failed after 5 years of use... Mire power and so much quieter... I also prefer the optional switch as I do not like having to run batches as I do like to reduce my Biomass by grinding and not throwing it out... Also less smell... There is enough power to grind chicken and smaller pork bones... Given long enough even thinner steak bones can be done. Good buy and easy installation even without using the instructions... Pretty intuitive if you've tackled such projects before.
