I bought one of these while they were on half price at Coles. They are pretty terrible. I didn't realise the instructions would require you to cover the egg in each cup with boiling water also. By the time you're done with all the pouring of the boiling water, you've spent about as much time as you would otherwise have done, poaching eggs in a small pot… and cleaning altogether 6 components is a lot harder than washing one small pot.
The end product is very inconsistent also, because microwave ovens don't have a particularly even radiation pattern, you end up with undercooked and overcooked bits. It's tragic. If the only cooking appliance I had was is a microwave oven, I think I'd set it on fire, and put a pot over the flame, rather than use this thing to poach eggs.
