Logitech be a great company , with great tech product . they have be make keyboard and mouse for a long time . which be why I be simply amaze at the craptascular installation guide that Logitech provide with they product . here be what you get when you open the box : 1 -rrb- keyboard 2 -rrb- mouse 3 -rrb- one instruction book , one legal mumbo jumbo book . 4 -rrb- a cord that connect to you usb 5 -rrb- \*\* a tiny tiny tiny little thing that look like a extremely mini usb jump drive . \*\* the fifth item I almost throw away with the box because I do not see it . item 5 should be insert into Item 4 . the Instruction Booklet DOES NOT mention this fact . -lrb- in any of the three language the instruction come in -rrb- . the instruction booklet be worthless . to paraphrase : plug it in and you be good to go ! no , it be not that simple . the only thing that I have find that simple and easy to use be a Apple product . this be not that . also , the instruction booklet discuss `` Unity Software '' ... no software cd come in the box , so I be confuse . how would the driver be install ? here be my attempt at provide decent instruction , which Logitech , for all its year of computer accessory experience , fail to do : 1 -rrb- unpack the five item . insert Item 5 into Item 4 . 2 -rrb- plug item 4 into you usb connection on you computer . position the other end of item 4 on you computer desk . 3 -rrb- log into your computer with you exist keyboard and mouse before turn on the new Logitech stuff . Trust I . I be guess Windows automatically find the driver and install it from the internet , but it will not do this if you be not already log in . which mean the new keyboard and mouse will not work and you 'll be stick . 4 -rrb- disconnect you exist -lrb- wire , in my case -rrb- keyboard and mouse . turn on the new Logitech keyboard and mouse . wait a bit for you computer to sense they and make they work . my computer do this `` sense '' and `` make it work '' automatically . Make sure that the Item 4 -lrb- which be the wireless sensor -rrb- be located on you desk in front of you keyboard and mouse , to make the keyboard and mouse detection easier . 5 -rrb- it work ! the Logitech troubleshooting guide really suck too . I be not really sure what you should do if you have trouble with you keyboard and mouse . to quote the IT crowd : `` have you try turn it off and on again ? '' because that be basically the advice the troubleshooting guide give you : check the battery , turn off and on and hope for the best . I try google the `` Logitech unifying software '' when I think that I be miss a installation cd and nothing useful come up . be the product that new ? or just that foolproof ? okay , so you know the installation guide suck , and installation be not as easy peasy as it could be because of the sucky instruction . about the product , though : five star . it look nice , work well , and be price well . plus it be Logitech , so you know it be good quality . ergonomic design -lrb- not really , but comfortable nonetheless -rrb- , feel good in you hand . a note for people who like they keyboard `` clicky '' : this keyboard be not clicky . it be pretty quiet when you type . final take : I like this product , would definitely purchase it again . BUT Logitech really need to up they game and fix the installation guide , and delete reference to `` software '' -- which might make user like I wonder if they package be miss the driver cd . compatibility note : this be a Windows 7 keyboard and mouse . it be NOT MAC COMPATIBLE . the computer I install it on be run Windows xp , and it work well with that too . I would not buy this product if I have a older version of Windows than that . to Logitech : 1 -rrb- the item 5 I reference above be really small , and easy to lose . pack it differently or it will be lose , throw away , or crushed inadvertently . a packing list so people know what be in the box would be great -lrb- no , your installation GUIDE , which be supposed to make this clear , DID not have it list clearly ... Item 5 and 4 be merge in the installation guide -rrb- . 2 -rrb- if item 5 be suppose to be plug into item 4 anyway , why do not you ship it out like that ? 3 -rrb- stop assume that you have design the greatest product in the world and it be so easy to use and wonderful that instruction and troubleshooting be unnecessary . tone down the `` so easy to use , no wonder it be # 1 '' outer packaging language . why ? because customer who have difficulty will feel that Logitech be assume that they lack the intelligence to make they magical keyboard and magical mouse work . 4 -rrb- make the product name `` googleable '' . create a troubleshooting guide and installation faq on you website for this product -lrb- and make it easy to find !! -rrb- . DO NOT use the same horrid book that you include in you packaging , be more helpful and complete in you instruction . a installation video would be nice . 5 -rrb- last thing : when you provide a email address for further information , do not underline it . because the underscore character merge with the underline in you final letter , make the email address unworkable . -lrb- in the letter you send out , the email address seem to have a underscore before the '' @ '' . which be probably incorrect . -rrb- seriously , you have not hire people that know this already ? 6 -rrb- FIX you installation guide and troubleshooting guide . yes , you product be easy to use . but people will have problem . it be you job to help they fix they problem , instead of just tell people that you product be so great it need no troubleshooting since it install like magic .
