Initially I was disappointed. Seemed expensive for what it is. However after using it, I am pleased with the purchase. It cuts whatever you load it with into small slivers - just enough to reward. No worries about calories in training and there is no way you could easily hold the amount of treats it can cut in you hand loose easily. Your hands stay clean. You have to learn what dimensions are needed o load. All in all, it should pay for itself. I clean in hot water with a straw cleaning brush. My only complaint (besides cost) is lack of directions.
