I bought this to make apple sauce. I knew I had to have the meat grinder attachment to complete the strainer, because it doesn't come with all the parts you need. (That seems stupid) I already had the meat grinder so I thought that would work. Wrong! Even though I had a KitchenAid meat grinder, it would not fit. I had to buy a new one. Finally I had the right parts and I was excited to try it out. At first I got juice and there was some dry sauce-like stuff coming out the little holes. I had only a few apples go through but then I couldn't get any more to go through. The mixer was getting too warm. I quit. Maybe it would work with raspberries but I'm not sure of that either. I would not recommend this strainer.
