I have been looking at this thing for months and finally got it. I am so happy I did! Blades are VERY sharp. It has a sliding lock to hold the blades in place and it won’t cut unless it’s locked. All parts went in the dishwasher so and came out with no issues. The only part that is a pain to clean is the top piece that pushes the food threw. It has grooves that food gets lodged in and you have to pick it out BUT I would rather do that than spend all the extra time mincing. Worth the purchase especially if you do meal prepping for the whole week! Your hands will thank you!
