Lovely
Color: Rose, Size: 1 Pack, Style: Combo
Love the clacking sound, it’s satisfying, the keys aren’t sticky, it’s a nice shade of pink, comfortable to use. Keys pop off easy enough for easy cleaning and are super stable when popped back on. The mouse is great two, it’s a two-in-one set up with the USB plug in so it controls both which is nice.

An extra separate dongle for the keyboard and mouse would make this perfect.
Color: Off White, Size: 1 Pack, Style: Combo
I picked up the Logitech MK270 Wireless Keyboard and Mouse Combo on a recommendation from our IT guy, and overall it’s been a solid buy for the price. The keyboard is the highlight. I’ve been using it for a couple of weeks now and it’s been great. It’s quiet, responsive, and just works every time without any issues. Setup was simple and I haven’t had a single connectivity problem. I do wish the rear feet lifted it a bit higher. Even fully extended, it sits more flat than what I was used to. That said, I’m adjusting to it and it hasn’t been a dealbreaker. The mouse is where it falls short. It gets the job done, but it definitely feels a bit cheap compared to the keyboard. Lightweight in a way that doesn’t feel premium, and just not the same level of quality overall. One thing I really wish they included is a second dongle. I’d love to keep the keyboard connected to my main PC and use the mouse with my laptop, but with only one receiver that’s not an option out of the box. All in, this is a reliable combo from Logitech. The keyboard alone makes it worth it, especially at this price point. Just go in knowing the mouse is pretty basic and you’re limited to a single receiver setup.

Perfect solution to a common problem
Size: 6-Foot Cable, Style: Rotating Plug - Single Pack
Power strips that have low profile plugs are fairly easy to find these days, but it's a lot more difficult to find one where the cord leaves the plug in the direction you need it to. This solves that problem. you can turn the prongs on the plug and any direction you need them to go. And it doesn't hurt that the design is attractive and appears to be fairly sturdy. I've been using mine for over a month at this point and I'm very happy with it.
