Just go ahead and spend the money on Band-Aids
This gadget is nice ... conceptually. However, in execution, it is flimsy, very difficult to use, the blades are almost impossible to change out, and it is an overall waste of money. It works ok for easy things like carrots and cucumbers, but you could slice those just as easily by hand. On the more difficult items (such as potatoes or other dense vegetables), the slices get jammed in the opening and you end up cutting your fingers fairly frequently. It just isn't worth spending [money] for.
