My wife has used this wireless keyboard for 2,331 days and it's still the best one I ever bought — get your own for Cyber Monday

Logitech's K400 Plus has survived daily use since July 2019 and shows no signs of failing. A Cyber Monday must-have.

Once upon a time, there was a moment when it wasn't Black Friday or Cyber Monday — but it was Amazon Prime Day in this particular example. Yes, I bought Logitech's highest-rated wireless keyboard in July 2019 because my wife needed something for her TV-connected PC, and boy, do I feel smart for buying the $23.99 Logitech K400 Plus from Amazon.

This thing must be nigh-on indestructible (hyperbole, do not take seriously), because it has survived countless drops from the sofa and even splashes of Diet Coke. Indeed, she's played World of Warcraft for hours with interspersed breaks of Stardew Valley — or was that Sun Haven? I don't know — and it's still going strong, albeit with faded keys. It's the most convenient keyboard you could buy.

An advertised battery life of "up to 18 months" is no joke; the Logitech 400 Plus seems to live forever, and I scarcely remember changing the batteries. Packaged with a USB dongle and AAA batteries, it's a real workhorse.

At least when you do run out of juice, you won't need anything fancier than Amazon Basics AAA batteries. I have a stack of these ready to go, but haven't opened any yet.

Is the Logitech K400 Plus a good keyboard?

Absolutely, it is. I doubt I'm making any revelations when I say that Logitech manufactures great keyboards (and mice) — anyone who has stood near a computer has undoubtedly noticed its peripherals and how long they last. Still, I wouldn't blame anyone looking for the best Cyber Monday keyboard deals for overlooking this deceptively simple option.

The keys seem a little shallow — because they are — but not to a point that typing feels subpar. On the contrary, I've used the K400 Plus in a pinch with a few keyboard-less devices like my Surface Pro X and typed out entire articles with the thing.

It's a capable little unit, and the touchpad offers surprisingly unique functionality with a separate, yellow, 'left-click' button mounted in the top-left of the chassis. It works better than you might think; I hold the whole keyboard like an oversized Xbox controller, my right thumb on the touchpad and my left thumb on the yellow button. Nifty.

Now, to be transparent, we are using a couple of Duracell AAA batteries in this keyboard right now, but that's only because I bagged a similar bulk-buy bargain on these coppertops years ago.

However, you do not need high-end alkaline batteries to keep this keyboard going for months. I know for a fact that I replaced Logitech's included batteries, and any brand works fine. Of course, if you're a Duracell fan, you can still pick up a 10-pack for $8.48 with similar Cyber Monday battery deals.

Old reliable. More expensive, but tried-and-tested Duracell batteries are almost always discounted during these sales events. Ditto for Cyber Monday.
