My general opinion is that this product is good. Is it a must? Definetely not. Will it make your life easier? Probably. However, it's definitely not easy to clean because food gets stuck everywhere. The blades are very sharo, so I recommend to handle them with care. Don't run your fingers over them because you'll end up with a minor cut on your fingers. The part that bothered me the most was the actual cutting part. It's a nuisance to cut large vegetables, such as potatoes. I had to cut my potatoes in half to use this thing so that they would fit over the blade. Overall, I think it can make life easier, if you cook a lot and don't have a lot of time.
