Microsoft Wireless Optical Desktop 2.0

When I connected this set to my PC, at first i was receiving some problem about the USB malfunctioning, that was probably just my computer though because after a few seconds the problem went away and i was able to use the keyboard and mouse. It did not come with any drivers but that wasn't a problem, I easily downloaded and installed them from Microsoft.com. This set is great and I would recommend it to anyone.

I really like this keyboard so I took a chance on this one, my old one finally quit working. This one did not work properly from the start.Had to return it.

Even brought this over to a local computer store and they couldn't get it to work. It was very cheap so I didn't care much but it was just paperweight. I couldn't get it to work wirelessly and since there was no wire I just couldn't get it to work period. Wish there was a wire if it stops working wirelessly. Useless.

Goes to sleep to often can't wake it up from hitting any key u have touch the adapter

this mouse is difficult put off battery -_-;

Great product

I really wanted to like this keyboard and mouse but I've just had so many problems with them that I'm taking them back.First the good things:- Lots of shortcut buttons to things like e-mail, browser, etc.- Fairly solid design- I like the way the keyboard was slightly curved but not too much like the Microsoft "Natural" keyboardNow the bad...It wasn't long after I bought the keyboard and mouse that the left mouse button stopped working intermittently. I read other reviews that said the same thing so I tried taking one of the batteries out but that didn't solve the problem. It's very frustrating to be trying to work and to have to click maybe ten times on a link or button in order for anything to happen. I have bought a replacement wired mouse and have that connected as well as this combo. After I've tried left-clicking ten times using the wireless mouse with no response, I use the second mouse as my "left-click" device. As soon as my replacement wired keyboard arrives, I'm taking this piece of junk back.As well as the left mouse button not working more often than not, the mouse isn't very ergonomic. With my hand on the mouse, I use my thumb and little finger to pick up and move the mouse on the mouse pad. The mouse shape is such that this is not easy to do. It's difficult to describe but the mouse has a very fat bottom (at "desk-level") and then it gets skinny at an elevation of about 0.5" above desk-level. So trying to pick it up from the bottom with my thumb and little finger sometimes causes my thumb and little finger to slip "up" the mouse. Sounds a bit rude but I hope you get what I mean.The last thing is that the keys can't keep up with my typing. I don't think I'm that fast a typer but maybe this is a general problem with wireless keyboards (hence my getting a wired keyboard replacement). When I type words that end in "rt", it misses the "t" almost every time. I work for a company that does reporting so I type the word "report" a lot and it's extremely annoying to have to go back and fill in the "t"s all the time.Also, the shift key seems to stay down for longer than it should. I occasionally get two capitalised letters at the beginning of a word instead of one. Maybe it's the design of the keyboard that's causing my finger to linger longer than usual on the Shift key rather than a problem with the signal but whatever it is, it doesn't happen on other keyboards.And the last thing is that the space bar doesn't register about 20% of the time. There have been other dropped letters too but these are the ones I noticed most.So, there you have it. This review hasn't been as bad for the second half because my new keyboard arrived half way through me typing it (whoopee!) so everything's back to normal. It's another MS keyboard, by the way - a "Digital Media Pro" for $22.77 (http://www.amazon.com/exec/obidos/tg/detail/-/B0002CPBUK/qid=1125618901/sr=8-1/ref=pd_bbs_1/104-7709379-7980766?v=glance&s=pc&n=507846) and it's great so far! Not a single dropped character.

Haven't plugged this in. It is supposed to be refurbished. Took a long time to get here and is filthy. It would take me 20-30 minutes to clean it up so I will probably just give it to someone and buy a new one. A waste of money. I did not buy this from Microsoft. Bought it from some other source online.
