They've ingeniously made them so that you can make the switch with minimal fuss. It's almost... convenient! They put these towels in a roll so you can put them on your existing paper towel holder (something I don't even have, come to think of it). I can't think of a down side.
Of course, I have to think people will find a downside and say it's too much to wash them, what a bother, not convenient to throw them in the wash, or they cost too much, and won't take into account the money they AREN'T spending on paper towels... but as wise people always say, ya can't fix stupid.
Meanwhile, I will await the reply from the company and hope that I am not disappointed in any of their answers. I'll give them a positive for now.
