What different between electric and manual meat grinder?

I used to make ground meat and sausage by myself. So meat grinder is a must-have for me. Normally I use KitchenAid meat grinder attachments. It's multifunctional but I need something more portable sometimes. Finally, I got this grinder. Now I can do my job anywhere in the kitchen. Believe me, you won't want to move a stand mixer frequently. This unit is solid. The motor is very powerful and works like a charm. 5 lbs ground meat is done in minutes. Normally I froze meats for 2 hours before grinding. That helps a lot. There is 3 size grinding discs for different needs. The medium is the one I like the most. It also comes with sausage attachments. Everything I need is included. I have nothing to complain, great buy.Click here for more info Best Meat Grinder In 2018 Quick Look At The Best Meat Grinders
