Although I do not buy this. But I saw the demo last year when the sales came up to my place. It seems really make your place in a very clean environment. However, it is really time-consuming on washing those parts after using each time.
And one more issue that I did not consider to buy, if
we provide a very clean environment to our kids, I 'm afraid that when they go outside or go to school, they may be easier to get virus/bacteria infection.
