MicrosoftWireless Laser Desktop 4000

Wireless keyboards are great because you can kick back, recline in your chair and sit several feet away from your laptop or desktop while having the ability to type from almost any location. A lot of wireless keyboards, however, have downfalls - many are just outright chinsy and break when you breathe on them, some are too heavy/clunky, others act as dust magnets and become so clogged with dirt and trash that the keys become unusable and unreliable. Other wireless keyboards have serious signal range issues or chew through batteries in a matter of days. The Microsoft Wireless Comfort 4000 keyboard, however, is a true winner. It strikes a good balance because it's well designed -- it's easy to grip, light-weight, and the keys feel great.I mainly bought this wireless desktop 4000 package because I needed to replace my busted old Logitech wireless keyboard. The Logitech wireless keyboard was plagued by a slow key rate (I type fairly fast, > 80 words per minute) and the horrible unreliable wireless signal resulted in me losing my cool and smashing the keyboard into oblivion. Violent rage aside, the Wireless Comfort 4000 keyboard is in a different league. The keyboard is very responsive and the keys are quiet. Additionally, the keyboard has a "sleep" button which is becoming more difficult to find on a vast array of the wireless keyboards on the market currently. It has all the buttons I commonly use as well as a nice layout that is beneficial for fast typers. The mouse is fine but nothing special, I already own one of those blue laser Microsoft mobile mouse 6000's so I don't use the included mouse regularly, I simply tested it out of the box to make sure it wasn't defective.Great price on a great wireless keyboard/mouse package. The keyboard alone is worth the $40 + tax I paid for it. The mouse is just an added bonus. Pull the trigger, best $40-$50 investment in a wireless keyboard you'll make.

This MS Wireless Desktop 4000 is an excellent keyboard/mouse combo. After one year I am fully satisfied with it. Touch typing with the padded pad and curved keyboard is comfortable and accurate. The keys are excellent touch and it is reasonably quiet. One accidental water spill into the keyboard seemed to cause no harm. We turned it upside down shook it well and then laid it on a towel. Next morning it worked just fine. I have customized most of the optional keys to suit my needs and they save a lot of hassle. I would really miss those keys.The mouse works well within a small space of 5x5, is smooth and all buttons and dial work as they should.The only problem is a false low battery report now and then. Too infrequent to make me search for the cause.We have just acquired another computer, and from the looks of the field today, we will go with another 4000.

My biggest complaint is unresponsive keys, especially in the numbers key pad (the enter button within the keypad in particular). I use an accounting system and use the numbpad all the time.Another annoyance is the hypersensitive mouse. There is probably a way to adjust, I just haven't taken the time as I am more concerned with the keys that intermitantly don't work or require a heavy hand.On the upside....it is wireless which is what I wanted and it was easy to install.

I bought this set for my husband. We've had no problems with the keyboard, however, the mouse is the worst mouse I've ever used. I don't even know how to describe it. It's sluggish and nearly impossible to use no matter what settings we used. I can find absolutely no redeeming qualities for this mouse other than it did work, just not acceptably. I finally just ordered him a new mouse. I went with the same Logitech Nano that I have and love!

This is the fourth keyboard of this design I've purchased for my office computers. I dictate documents or letters rarely and do 99% of my document production (and of course e-mails) myself, so keyboard ergonomics are critical. The keyboard layout is great - I particularly like the nice, big, easily-stroked DELETE key - and the rest of the keys are big enough and spaced apart enough that a concrete-fingers like me isn't going to be hitting the wrong keys as I blast away. The wrist rest is a huge help and makes this a very comfortable key board to use for extended periods of typing. The wireless feature eliminates desk clutter. If you don't want/need the "smart" gadget keys it's ready to go right out of the box (you need two AA batteries). Plug in the receiver module to your USB, and start typing.The mouse that comes with this is an absolute piece of crap. Clunky, hyper sensitive and has a bad habit of losing its connection with the receiver. All of the mice that have come with the keyboards of this line I've purchased I tossed. I just bought the fourth keyboard and *the mouse didn't work at all!* Couldn't get it to connect, even with the mouse software installed.This would be a five-star review if it weren't for the mouse. It's barely a three because you're paying for a mouse that's poor at best, worthless at worst.
