Welcome to our forum.
Do some research on Microban, and you'll decide that not only is it completely ineffective, but it contains stuff that you really, really don't want to be soaking in.I wouldn't have it if it was free, much less pay for it.
That is just a little extreme, there are more nasty things in higher concentrations coming out of your tap water than the microban surface in the final product. I won't say its effective or worth it, but I think your being a little alarmist.
