It's a little better than satisfactory because at least it can cut a lot of even slices quickly, and that's not something I can do by hand. But overall, except for the metal blade, it's all plastic. You can't lean on it or put to much pressure on it. It doesn't cut as smoothly as you see at your deli counter, and it does work at a much slower pace. But for basic home use of small items and not really, really big jobs, it's more than adequate. Power It's not very strong, but if you don't force it, it does a decent job. We had a large, whole slab of bacon cured and smoked for us by our neighbors. But then we were left with the task of slicing it into bacon. This unit did a pretty decent job although I would have liked it if could have sliced the bacon a bit thinner. My Dad uses it all the time for slicing salami and pepperoni. Hard cheese are okay (but not too hard); soft cheese can be messy. Safety Follow all directions and use all safety items! Ease of Cleaning The plastic cleans up easily Durability We don't use it a lot, so it's lasted us a good number of years.
