Do not buy in amazon, it is worst, the seller is worst.
After 6 months, mouse and keyboard stopped working & i called dell for replacement. Dell team said, they will help, but they needed serial number, and surprisingly, i checked my keyboard and mouse and there were no serial number, i was fooled and i got fraud device.

Love it.
Just got it and so far it is great. I have been using a Logi K545 and I hate it. Every time I use it I swear I'm going to throw it in the garbage. The keys are so sensitive that that add any key you hit or even brush against. Takes longer to correct the errors than it does to type something. The new Dell is so smooth and so quiet no key clicking at all. BUT IT! Hook up was a breeze, add batteries, included, put dongle in USB port and turn on the keyboard and mouse, that is it. Using Windows 11. UPDATE With in a few days two of the keys stuck down, the 3 and 6. Have asked for a replacement we will see how that one works. Took away 4 starts. Cancelled the replacement too long to deliver it. Now waiting for refund!!!!!! SECOND update Received my refund everything worked out would do business with them again put 4 starts back.

Mouse scroll broken out the box
Bought 6 months ago and never used as we accidentally purchased the American layout. 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

Great package to replace my damaged set!
My rabbits got on my desk accidentally and chewed off the rubber cover on my mouse wheel and lost some keyboard keys so I had to replace both. Good thing they are cute! This product is perfect for my AIO desktop, USB receiver was plug and play and I had everything working in 2 minutes. I also love that they provide Duracell batteries for both items, not cheap, generic brand ones that will die quickly. A really nice touch that I appreciate as a heavy daily Photoshop and Lightroom user with probably more than the average mouse and keyboard clicks.
