Great value

Great price for display to HDMI cable. I don’t know anything about it, but my son says it works perfectly!

Very comfortable to use
Style: Combo, Color: Rose, Size: 1 Pack
This is a nice keyboard/mouse for the money. I ordered it in pink because it will help me to keep it separate from others I have. I have a tendency to forget which mouse goes with which keyboard. The color makes all the difference. In addition this works well and has a light up indicator for the caps lock which my older one does not. That was annoying to look up and see that everything was in caps by mistake. Good product.

Works great, very happy with it!
Style: Combo, Color: Black, Size: 1 Pack
I really like this keyboard and mouse combo! It arrived in perfect condition and works exactly like it should. Setting it up was incredibly easy- you just plug in the little USB receiver and you are ready to go.
The keyboard is comfortable to type on, the mouse is smooth, and the wireless connection has been flawless. If you need a reliable, no-nonsense setup for daily use, this is a great choice. Highly recommend!

Perfect, Budget‑Friendly Combo
Style: Combo, Color: Black, Size: 1 Pack
The Logitech MK270 Wireless Keyboard and Mouse Combo for Windows, 2.4 GHz Wireless is a great, cost‑effective set of everyday desktop accessories. It connects easily with a single USB‑A dongle, gives you a full‑size keyboard with a number pad and media keys, and includes a compact, comfortable mouse that works smoothly for typing and browsing.
Battery life is excellent (keyboard and mouse both last many months), and the 2.4 GHz wireless connection stays stable without noticeable lag, so it’s reliable for office work, school, or casual home use.
Overall, it’s a simple, plug‑and‑play wireless combo that delivers solid performance at a very reasonable price.
