Summary: It measures 8.7 x 0.2 x 4.7 inches. I have larger hands, so I found that the ergonomics were completely incompatible for me. This device may work for tiny hands with no nails (there is no space between the keys). I would have certainly returned this device for a refund, but it developed discoloration on both upper corners; which is weird because this produce comes with a Bodyglove "like" protective cover that completely envelopes the device for save mobility.
Summary: I love the design and comfort of this keyboard; it would be the perfect keyboard for me... if it worked. The first keyboard I purchased mostly worked, but the left control key had to be pressed down very hard for it to recognize the key press. I returned it for a replacement, but the second keyboard was even worse because the shift keys sporadically didn't work with certain key combinations.
Summary: The mouse is ok as a mouse, but I find it almost unusable. It is way too sensitive or something, because a normal mouse you just lift an inch or so, and it stops tracking so you can go farther. With this one, the lift is at least three inches, way too high, and then as you set it down it also tracks.
