Query: Makes the perfect egg!

I keep this egg cooker on my countertop, and use it frequently. It's so easy, and I just cook my eggs for 9 minutes in my 700 watt compact microwave oven, let them sit for a while - sometimes I forget them altogether, but the cooker makes very good hard boiled eggs. I have never cooked less than 4, and always make sure I have enough water in the bottom. No explosions here.
