I’m in love with this little chopper ! It is a 3 cup capacity and absolutely perfect size to make salsa or chop nuts , both of which I have done ! The measurements are clearly listed on the side of the clear plastic container . The lid secures  tightly to the top, but is easy to get on and off which I find very helpful with arthritic hands . This has a two button function high or low . 
It’s easy to clean up ! It is also perfect size to store in a cupboard or leave on your countertop if you would like .
