I've got one of those, picked it up at Walmart awhile back. Handy ah heck. When the AC is pumping seemlingly constantly, 25 minutes of stove top cooking doesn't appeal to me. (Small kitchen anyway) and with this thing I just dump it in, hit start, if I forget I was making something and find it the next day, no biggie. Done that with the burners on the stove a few times, man, burnt teflon stinks.
For "chefs and cooks" ok, it's lame. For those of us who eat whatever is handy, it's great.
Just make sure to take out the middle part if you're making one of those premix bags of noodles and stuff otherwise it's a mess.
