Summary: Horrible response between keyboard and mouse. The worst I have ever seen. Others have complained about this but still give it 3 or more stars? I don't understand how reviewers can complain about the REALLY bad lag between keyboard and mouse and still give it more than 3 stars.
Pros: Worked great.... until the receiver was mildly hit.
Cons: Accidentally bumped the receiver while moving my computer,now the Whole thing is useless! I'm buying Logitech from now on.Not only does the Logitech Unifying USB Receiver work with multiple devices you can buy a replacement.
Excerpt: I agree with a previous review. I like almost everything about this keyboard except the lack of a caps lock light. Drives me crazy, especially when keying in a case sensitive password and not knowing if caps lock is on. I have never seen the supposed caps lock indicator on the screen.
Excerpt: Bought this for my home office. Needed something dependable. Yesterday, after only 5 months, the mouse died. Took it back to Staples, but apparently they no longer care about customer service (seriously...they told me that corporate policy had changed about 8 months ago and now they were strictly enforcing their 14 day return policey...they then said, "it's Microsoft's problem, not theirs!). So, now I have to get a new mouse. What a piece of junk!
Excerpt: RANDOM DOUBLE CLICKS, RANDOM EXTREME SPEED-ENTERS DATA BEFORE BUTTON IS BARELY DEPRESSED, DATA ENTRY ON DEPRESSION AND RELEASE OF BUTTON. NOT RELIABLE FOR ANY IMPORTANT DATA ENTRY / PROJECT,USE AS A TOY ONLY.
Excerpt: Keyboard doesn't register strokes at times. As a fairly quick typist, I find that sometimes I have to repeatedly strike the same key in order for it to register. Not a pounder, but I have had to on occasion. I lose parts of words and have to backtrack to make sense. I called microsoft and they sent me a new keyboard. Same thing happened again. I've never had this problem with any other keyboard (am on Laptop right now and all okay).
Excerpt: First one didn't set up, returned it for a replacement. Second one worked for a week and then the keyboard lost connection although the mouse worked fine. This product was just too frustrating for the price.
Cons: Difficult To Set Up, Doesn't work, Slow Connection
