Very funny. However I have a better useless machine at home, my so called vegetable dicer & slicer. The company claimed to have a lifetime sharp blade but it hardly cuts a cucumber or tomato. LOL.
Pretty old, annoying, simplistic, worthless, yeah.... lol! Whoever designed it probably loves it though.
I dont think its useless, it give us fun, & fun is the best practice for the body, so this is useful not useless.
Hay Jahangir!!! People make your useless machine useful... some one wants to get it for finger exercise...or its a source of laughing... hahahahahha
