Had a demo done recently and received a token free gift. Sales person is nice and professional, no pressure to buy. This product is not for everyone due to high cost. The product does exactly what it says and the cost is very clear. There is no cheating, hidden charges or false promises.

I didn't buy it because there's no need for my household. But for others in need of such high level of cleanliness or with cash to burn, then I can fully understand why they would buy it. I wouldn't call them suckers. Those who "invest" in obvious ponzi schemes are more foolish in my opinion.
