Six weeks ago, my 1980s plastic grinder, which had a small crack near where it attaches to the mixer, cracked further, allowing a small amount of the food I was grinding to escape out the crack.  When I saw the steel replacement grinder on sale, I bought it.  I made your Thai chicken meatballs with the new grinder.  I always seem to let the meat pieces I will grind stay in the freezer a little too long, and this new, steel grinder handles the harder pieces with aplomb.  I like the 3, not just 2, grinding size discs as well as the sausage stuffing material. [This review was collected as part of a promotion.]
