Star treatment for mashed potato (and anything else you'd like to mash!) ... nothing more to be said...
This one doesn't rust and the difference to the metal mashers is the central handle, sturdy good ergonomic grip. The metal mashers either have a bend to one side or two metallic bits leading to a handle, making awkard for washing as well.
Good choice if you purchase this and in the top ten for Tupperware sales in Europe!
