hello , I buy this item from my University 's computer store at a severe discount down to $ 40 . at this price , the combination be a steal , and I think it will be spectacular once I can connect my laptop to a large tv . there be some minor issue with setup , but all be fix by reconnect each component . = hardware = the material use to make the keyboard be not quite at $ 100 standard , but the mouse be attractive and have some good attention to detail . I be currently write this review on the keyboard , and I must say that it be a improvement over my laptop 's keyboard . there be good resistance and travel on the key , and the keyboard be equip with plenty of extra function , as a laptop 's keyboard might . = functionality = the mouse have a laser sensor , and while it register very slight lag when compare to a wire gaming mouse -lrb- which be to be expect -rrb- . it have a very slight difficulty register extremely fast swipe , so this will not be use for gaming under the table sensor functionality . for daily use , I be certain that I would forget that it be wireless . the air sensor use a accelerometor , and be very accurate for navigate the desktop . with a distance of approximately 30 foot , the mouse work passably , with some deterioration in accuracy . I do not believe that it would reach its advertised range of 100 foot without severe accuracy deterioration . I have not test the keyboard range , but I expect it will outperform the mouse . the mouse software be fairly intuitive , and allow for mapping of many function to the proprietary gesture and media key located behind the scroll wheel . when active , these function fairly well . give its unique accelerometer feature , I test its performance as a gaming tool . initially , I expect that it would add a interesting dimension for non-competitive gaming , as it be quite accurate . I do not predict that it will be sufficient for competitive gaming , because of the limitation of turn , understandably . upon play the first two chapter of l4d on easy mode with the air sensor functionality , I be impress by the accuracy . as expect , I would never use the option in competitive gaming , but it hold up fairly well . from this information , i expect that daily use will be fine , give the level of accuracy achieve in game . for hardcore gamer , as I use to be , this be still not as good as a regular table mouse , but probably the closest to have wii-style gameplay on the pc . as I be typing this , I be notice that the keyboard will occasionally spaz randomly , perhaps due to quick typing . it do not seem to be much of a bother , but should be note . = BOTTOM line = overall , for $ 40 I be satisfy with the purchase . however , the quality definitely do not garner a $ 100 + pricetag .
