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. Review: Amazing product ! - Compact, efficient, durable. I’ve tried plenty of options as I am renewing my office space. This I can say it’s the best. Don’t pay $$$ when you can get something like this affordable and super reliable.

Best options out there ### ⭐⭐⭐⭐⭐ Sell Prp Km5221w wireless Keyboard and Mouse *by B***E on October 21, 2025* My old wireless mouse was causing me all kinds of issues. Costing me extra work. New mouse and keyboard eliminated all that frustration. I get my work done in very quickly. I should have done this months ago. Easily installed and a very reasonable price. After two and a half months of use the mouse has started being an issue. I’ll be working on a document and all of a sudden the cursor start a running all over the document. I have auto delete to reset and hopefully I get back to the work I was doing.
