okay I have be use this for about 3 week , and here be a update review : I have a friend with the IR version , and after use he for a bit , and loving little gadget , i get my this bluetooth version for my to-be -lrb- now realize -rrb- htpc . -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- the good : come with a Bluetooth 2.0 dongle . pair without fuss . excellent battery life . backlight . great button travel and feel . -lrb- for the size -rrb- mousepad work well . good range . -lrb- line of sight -rrb- fit in pocket . `` la-ser '' pointer to play with pet . can use while charge . charge quickly . good price . no software require . -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- the Bad : strange placement of some key - not unlike some laptop . no f9-f12 key . -lrb- which i only realize after a week of use . . tell ya how much i need they . only one shift key . Range stay good , but connection falter quickly if anything be block signal . Mousepad kinda get in the way of quick thumb-typing . -lrb- but then , where else could they put it ? Mousepad detect not as touchpad by OS . no scroll-wheel function . no software for extra configuration . -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- use this on and htpc with Windows 7 Ultimate 64bit . quad-core , 8gb ram , yada yada . while the line of sight range be about 20 foot , if anything get in the way , the signal break up break up pretty quickly . I have mount mine on the wall above the television , so it be always in range when i need it . if you be look to hide it inside a case , this be not for you . if you stay within 5 foot , then block it be fine , but not a realistic option for a living room . the official Bluetooth range be tote as 10m , or 30 foot . I have never see a single BT device reach this range and stay reliable . this device be no exception . that be say , i can still use it from my kitchen - past the couch , table , and some step . I have be use it while set up the fine matter of my htpc , so I have be use it for about 2-5 hour a day while watch , typing , mousing , typing more , and set up xbmc and I have yet to charge it . I have use the backlight -lrb- which can be turn on and off -rrb- for about 1\/3 of the time . plus lot of harass the weinerdog with the laser pointer , which be very bright and have fantastic range . while I be not a teen-aged girl , I be not too comfortable with thumb-typing , but I have quickly become adept at typing with this thing , even though have the mousepad on the right side make it less than ergonomic . I have even start to type without look . my only real beef with the typing action be that there be only a single shift button on the left side , so enter a capital a , w , s , etc. , be a little weird . at first , i woudl hit teh BT Pair key wheil blindly hunting for the esc button , but i break myself of that habit . I refer to it as a mousepad because while it look and act like a touchpad , Windows 7 detect it as a regular mouse , so you lose some of win 7 's touchpad function , like edge cruise , and can not be configure separate from a regular mouse . but the mouse action be very easy to use , it have tap-to-click -lrb- which need a super-light touch -rrb- , and the mouse button placement be good . there be a easy to use Page up\/Down , but there be no mousewheel-scroll . the cursor key be located between the two mouse button . use the `` fn '' -lrb- like a additional Alt\/Shift\/Ctrl , e.i. modifier -rrb- key , you can utilize many other function and key , such as : Media key , backlight , Page Up\/Down , mousepad orientation , Windows Key , Delete -lrb- same key as backspace -rrb- . it have indicator light for Bluetooth connection , signal activity , capslock , and charge status . after turn on , it re-pair in about 3 seconds . I do not think it ever go to sleep . it can not pull a computer out of sleep but that be because Bluetooth do not remain active during sleep . however , the IR version CAN pull a computer out of sleep mode . the charge cable split off another female usb , so you win ; t lose a usb port when you charge it . use a somewhat-common usb end . i can also charge my cellphone-telephone with it . oh yes . . the disc that come with it contain Java \/ . si install file for Symbian\/Android\/gayPhone . I have a Nokia that run Symbian 6.0 , and it paired easily and work pretty well . though i really see no need to sue this with a phone unless you use you phone as a media player connect to a distant display . since I first peruse the other review on this , I have see MANY very negative review show up on this page . perhaps Amazon get access to a bad batch . I get mine from a 3rd party - CE Media . this be 100 % worth the purchase , and I be very impressed with it . no regret , whatsoever . and be a big tech nerd , I be fairly fussy about device functionality . Update : use this pretty much every day , for about a month , i finally have to charge it . only take 28 minute . still very ahppy with it .
