How lucky you are! I've been looking for one of those! I use it for slicing breads, vegetables for lining terrines, obviously for meats and deli, it's great for when you are dehydrating fruits/veg (ie: decorative chips) because it gives you paper-thin, even slices.
Not sure which model you got: is that the industrial one with the belt or just a deli model?
If you're not getting enough use out of it, feel free to send it my way!
