this be easy to use and work well . I literally take the keyboard out of the box , insert the transceiver -lrb- which have a storage spot on the back of the keyboard -rrb- into a usb port on my computer , insert two AAA battery that be include into the keyboard and the keyboard start work . the keyboard be approximately 13 inch by six inch . this give I much more flexibility when I be work at my desk and have a bunch of papers in front of I . I can move the keyboard around my desk with ease . my only complaint be that the keyboard do not have little pullout leg that allow it to be raise at a angle . if I be rest the keyboard on my lap it be not a big deal but I be usually work at a desk and I be use to a keyboard at a angle . this be a great product at a good price . I do with be could be raise at a angle though .
