I be go to write a semi-humorous review of this at the point that only 5-10 key be break , but at this point , I can only find 3-4 key that still work . it look absolutely wonderful in the dark , but it be difficult to use unless you have a hard , flat surface to put it on , and in less than a week of operation , I be ready to drop it in the trash -- not worth my time or postage to return it . get a Logitech wireless instead .
