I absolutely love this keyboard and mouse . it be so easy to set up . plug in the usb piece -lrb- it look like a jumpdrive -rrb- and from there my computer read the new equipment . then all I have to do be pull the tab piece from the battery compartment of the keyboard and the mouse and that be it . there be a power button on both so you can turn each one off individually or they automatically go into hibernation if not use for a few minute . I love how responsive the mouse be and the fact that it have a back and forward button right on the mouse . the scroll button work super fast . the keyboard be very comfy . it have a display to tell you how much battery power it have leave . the f-key be preprograme and have little icon on they to tell you what they can be use for . that be especially nice since before I have pretty much never use f-key . there be also key on the board for music -lrb- next , repeat , volume , ect -rrb- and I also love that . one other feature that I love the most be the button to pull up the calculator and its right on the keyboard . maybe other keyboard have this feature , but my last one do not , so it be nice not have to go and find it or hunt for my handheld one when I be help one of my kid with they math , or do my own math . I really can not think of anything else that I would like add to either the mouse or keyboard .
