I didn't like three things so I sent them back. It doesn't get hot enough to kill bacteria. I can put my hand in front of him with no problem. Also not a good item for the elderly, if you have even a little bit of arthritis, the handle is too hard to squeeze or hold for any real time. (my poor fingers) and finally the pressure wasn't strong enough to loosen the foam? hmm, and it took me 4 times as long to try if I could pick up a sponge and be done with it in less than 3 minutes! Hard to believe someone said they cleaned the whole oven with it lol
