Who does all that testing and how do they pay for it?


Insurance companies !!!

insurance is mandatory , 1 or 2 prevented lawsuits would
pay for several studies and a research facility.

my keyboard is not cooperating with me this morning so
I need the extra strength to bang on the keys to ensure that each character is placed in its correct position.

well , as it stands we only have testimonials from users of
