The first thing I tried out with the Expert Prep Pro was some scones, using the dough blade and a mixture of high, low and pulse speeds. It came together so quickly with no mess and fuss. I am most excited about the spiraliser feature though and love that you can prep everything together so quickly and easily. 
It's also really stylish and looks great in my kithen. The only slight downside is that it needs a lot of space for all the extra blades and discs but it's worth it for the range of functions.
