I am satisfied with my purchase. I had another cup fried all aluminum of the same brand that has held for a year. After a few uses, the plastic device seems solid enough. The rack system allows you to cut straight potatoes, which was not the case with my previous device (had to force on a lever system, it was going wrong and if the blades are broken). So much for the fries and vegetables not too hard. Not tried with carrots. Good value for money.
