Old keyboard and mouse finally gave out so decided to give it a go and get used to it. Mouse has scrolling issues straight out the box, scrolls up one then down once so practically unusable Review: Not really compatible with Macbooks - I bought this to use with a Macbook and monitor. I probably should have bought an Apple product. The keys don't match the Mac keyboard which is really frustrating as I have lots of shortcuts set up for the 3d modeling tool I use. I was hoping I could use the Mac's built-in Bluetooth to connect it but no, I had to use the USB dongle provided. Of course, new Macs don't have old USB ports so I have to use an adaptor. The keyboard also feels very 'clunky' to use - don't know how else to describe it. I've never made so many typos. The mouse is super lightweight and feels flimsy. This set might be good for occasional use but not day-long intense work. ## Features - Enhance your all-day productivity with this RF 2.4GHz wireless full-sized keyboard and mouse. - Programmable keys and scroll wheel allow you to gain quick access to your frequently used shortcuts - The native 1600 DPI mouse offers preset DPIs of up to 4000 adjustable via the Dell Peripheral Manager, offering accurate tracking across a wide range of display resolutions - Work with one of the quietest wireless keyboards whether on a conference call or in proximity with others.

The keyboard and mouse set comes with original Dell batteries that last long but depending on usage, I cannot tell the exact number of months or years. I'm using one with original batteries and after 7 months, still same batteries are working fine. ## Customer Reviews ### ⭐ Mouse scroll broken out the box *by A***R on 16 April 2026* Bought 6 months ago and never used as we accidentally purchased the American layout.

I had nothing but trouble with the mice. Keyboard seems OK. Worked OK to begin with then files I was working on kept on being asked to be deleted and text was randomly deleting itself. Googled it and apparently it is a common problem with their wireless keyboards and mice. People with similar issues had to revert back to wired connections or they bought logitech. ## Frequently Bought Together - Dell Pro KM5221W Keyboard & Mouse - Logitech C920x HD Pro Webcam, Full HD 1080p/30fps Video, Clear Audio, HD Light Correction, PC Camera Webcam, Works with Skype, Zoom, Facetime, PC, Laptop, Mac, Tablet - Black - Logitech H390 Gaming Headphones, Wired Headphones with Mic, USB Headset with Microphone for PC, Noise Cancelling Microphone for Video Meetings, Music, Gaming - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/404703649-km5221w-pro-wireless-keyboard-and-mouse-combo-programmable-keys-battery](https://www.desertcart.be/products/404703649-km5221w-pro-wireless-keyboard-and-mouse-combo-programmable-keys-battery) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-16*
