Dell Pro KM5221W Keyboard & Mouse

Muy buena compra, buen precio, fácil de adaptar a mi compu y sin cables.

Excellent keyboard! Just be patient opening the battery opening; I noticed it was like slightly stuck on one end; a thin blade carefully used made it so it popped right open. the USB transmitter slipped right in a USB opening in my computer, and it works super it comes with a nice mouse, but I like my microsoft bluetooth mouse and it worked immediately with it.This keyboard is better than the one that came with it. :)

i though the mouse was bigger my bad, else is working perfect

I ordered and received this keyboard/mouse for my new Dell Win 11 Desktop. I plugged the wireless adapter into a USB port on the front of the computer but the mouse and keyboard were not detected by System Manager or Window Settings. I informed Amazon and they refunded the purchase price but did not want me to return the equipment. Later I tested the keyboard/mouse with an older Win 10 desktop and found that they worked. After I studied the equipment manual for my Dell desktop, I found that the front panel USB ports were for high speed devices and the rear panel USB ports were configured for accessories. I plugged the wireless adapter into a rear panel jack and Windows Settings detected the keyboard and mouse. So I'm writing this review, even though I got the keyboard and mouse for free, to let everyone know to try a different USB jack if it doesn't work.

Works perfectly

At the time of this review, I've had this Dell combo for almost 4 months. At the time of purchase, I had looked at multiple options for keyboard/mouse combos and landed on this one. There were a few reviews at the time that caught my attention, "keys stick," "mouse issues," etc but at the time I assumed they were one-offs. This product being a Dell, from Dell was enough for me to take a chance. I wish I had not.I'll start off by saying this combo is being used in an office setting during a normal M-F 9 to 5. There is no excessive wear and tear. Almost immediately, I started receiving a "mouse battery low" error, that is lovely enough to be shown as a pop up window that won't time out. You have to manually clear it from your display every time. This error came within the first two weeks of use. At first I thought, no problem, the batteries that shipped with them wasn't name brand, may have just been bad batteries. So I changed them to Duracell Pros. I still continually get this error daily even with the first set of new batteries and an additional set. Plus the pop up is annoying to have to clear multiple times throughout the day. Second issues with the mouse is that it looses its mind at least three of the five working days. It jumps from one portion of the screen to the other, 'double clicks' when I only click once so every email I click on opens up or pages/items move when I don't want them to, etc. Overall, bad mouse.The keyboard does not fair better. The keys do stick. Badly. Again, this started happening early into the purchase, probably a month. It's annoying as well especially when its the function keys or Enter, then all kinds of background tasks are trying to open and I can't do anything except for turn the keyboard off and rake the keys trying to unstick the one that's stuck.With the issues between the two devices this combo is definitely a distraction and not in a good way.

I love that there is only one dongle for both the mouse and keyboard. The mouse is the perfect size and moves around very easily. The keyboard is is sleek and does not take up much room. The keys are quiet when typing (some keyboards are loud and clunky). This is a great, easy purchase for a college student or entry level employee. This set is perfect for a home office or even on the go! Light and compact, you can take them anywhere if you prefer not to use your laptop keyboard.

An inexpensive DELL wireless combo keyboard and mouse that uses a single USB dongle to wirelessly connect, in my case an MS Windows 10 laptop. The mouse hase an on/off switch but the keyboard doesn’t. I believe there will be an LED that will turn on when the AAA batteries are exhausted of their electro-chemical reactions, but since I just started using the keyboard I don't know. Other than that it is a plain typical no-frills set of i/o devices that work as advertised. The keyboard and mouse automatically were recognized by my MS Windows 11 laptop. The mouse is not a gaming mouse, but it seems responsive to movement. The keyboard is noiseless and is a full-sized black typical keyboard with a full complement of a numeric keyboard keys on the right side. The connectivity between the devices and the laptop seemed adequate for my purposes on a desktop.
