Our friends bought this model/unit after seeing the one we had (see my review) and realizing that it was too much plastic and not enough power for them. THIS model is much, much better. When time permits, we go over to their house and use theirs instead of taking ours out and being disappointed. While this unit does still have a lot of plastic parts, it's designed a lot better. The suction feet keep it from slipping/sliding. It appears to have a bigger blade. The movement of slicing is much smoother. My hands seem more protected. Adjustments are easier and a lot more accurate. We can slice meats and hard cheeses much cleaner and thinner with this model. If you have a lot of that to do, then it's worth the extra investment in the best slicer you can afford. Power Nothing's as good as the full metal ones at the deli counter, but this is more than adequate for home use. Safety Follow the directions! Ease of Assembly Easy to put together.
