The Perfect Keyboard

Reviewed in the United States on January 15, 2015

Size: Pack of 1Verified Purchase

I bought this keyboard solely to use with my Amazon Fire TV as I use it to make navigating Kodi and web browsing a ton easier (requires a rooted Fire TV for the web browser) you'll also need a keyboard to install a custom recovery to the Fire TV and since I didn't have one I bought a junky, wired one at Walmart and after seeing this wireless keyboard with a touchpad for only another $10 I took the wired back and ordered this. Since it's Logitech you know you're getting a solid device that works well for a great price. I've been using a Logitech wireless mouse with my laptop but could have used this keyboard when I had my laptop connected to my TV which I no longer need since I have a Fire TV. I assume it can also be used with other internet streaming boxes as long as they have a USB port and recognize USB devices. This keyboard is truly plug and play as it worked immediately with my laptop after plugging in the USB receiver and was the same case with the Fire TV. The only drawback with that is I couldn't even use the Logitech "Mouse and Keyboard Settings" with this keyboard as I thought I could use it to map keys and adjust the touchpad sensitivity (which you'll notice is up pretty high and can be all over the place) but no matter what I tried I couldn't get it to show up yet my Logitech mouse would. Maybe this keyboard isn't able to have it's settings modified. The shortcut keys and Windows function keys are a nice addition and surprisingly most work with the Fire TV (such as the Home button, the Sleep button, and function key actions.) The keyboard is sturdy yet light weight, has a nice sleek design, the batteries haven't needed changed yet, and the key presses feel good. The only slight con is the keys are a bit smaller than what I'm used to so I do make more errors although I don't type correctly to being with so for other people this might not be as much of an issue. There is a reason so many people use this keyboard, it does everything you need and works with just about everything. So if you need either a wireless keyboard or mouse you might as well just buy this keyboard and have 2 for 1, and paired with a dedicated Logitech wireless mouse you basically have the perfect setup for whatever you need to do.

It does everything it needs to, but wish it was more customizable

Reviewed in the United States on November 14, 2023

Size: Pack of 1Verified Purchase

If you're looking for a small keyboard that has a touchpad 2-for-1 that you can use at a respectable distance away from the computer, this is a GREAT fit. This is a great value for the price point. We use it in our living room to control the TV/computer from the couch.

PROs: Keys are crammed together which makes this take up not much room. Touch pad is reliable. Connectivity hasn't been an issue, however we don't usually test it from far distances. Keyboard keys I find responsive and very usable, though sometimes muscle memory wants to see the keys spaced further apart.

CONs: I wish some of the keyboard MACROs/functions were customizable (as far as I know, they are not). For instance-- swiping upwards will scroll the opposite direction than what a standard touchpad would normally do. Also, there is a shortcut swipe on the touchpad that reveals all open windows on the computer-- I wish I could disable this shortcut because it accidentally pops up often and every time it happens when I don't intend for it to.

In all, for the price point it will do everything you need it to do. 10/10 for the price point and value, but I do wish some of the device's shortcuts and functions were customizable.

Nifty keyboard for Mac Home theater PC

Reviewed in the United States on February 14, 2013

Size: Pack of 1Verified Purchase

OK, I've only had this a few days, so I can make no claims on durability of this unit.

It only gets 4 stars because of it not really being 100% Mac compatible-- The manufacturer doesn't claim it to be Mac compatible, but come on guys, it already works pretty good with a mac, how much more effort could it be to get this unit to work seamlessly with a Mac?
Perhaps this is bad form in my rating the product 1 star less for something it doesn't claim to support-- sorry, I guess I am a little opinionated on this issue.

I was a little taken back upon finding out that this device is not bluetooth. It has a little wireless adapter that takes up a USB port. Not a problem for me, but not what I was expecting. I guess I didn't read up enough on the interface before buying. The supplied wireless USB thingy works fine. I can move all around my 14x14 room without even a hiccup on this keyboard. (I had frequent problems with my Apple bluetooth keyboard and mouse-- which I attribute to their age at this point (9 years old).)

First of all it works pretty good with my mac mini even though logitech doesn't claim to be mac compatible.
The keyboard works like it should, and the track pad works fine for basic mousing around, but it seems not all of the other gestures work as the directions indicate they would work on a PC. Some gestures work fine, like double finger scrolling & tapping for mouse button presses. For me, these are the most important, as it greatly simplifies my use for a home theater pc

The usability of this unit is great. You should keep in mind my intended use for a home theater pc. My kids will be using it, as will I. We usually sit on the floor or on a bean bag chair. So this keyboard will be used at every conceivable angle, and it will be rather infrequent that it will be used on a desktop type surface. Mostly one finger typing rather than the typical touch typing that desktop use would entail.

The light weight of the keyboard and compact design enhance the use of this as we move around the room and move between programs. It is difficult for me to explain why, but the convenience is much higher than my beefy apple wireless keyboard which I will be repurposing. Perhaps is is simply because it is shorter and much lighter.

Logitech has made it convenient to use the trackpad as a "flying mouse" with an extra mouse button in the upper left, and the gestures simplifying mid air use.

With use as a TV PC, having one device instead of a mouse and a keyboard is tremendous improvement. It is further enhanced because my young kids never seem to be capable of keeping the old mouse and keyboard near each other (necessitating a secondary tethered mouse and keyboard when using my old Apple keyboard and mouse) I have removed the tethered devices, and I am now solely using the Logitech wireless-- so far the kids haven't managed to loose the keyboard.

Possible downsides...
1) The keyboard is a bit compact, and might be slightly frustrating if it were used for heavy typing
2) I find it a bit awkward using a trackpad on the side of the keyboard when going back and forth between typing and "mousing", but given my use as a keyboard for a TV PC, I have not found a better solution, as everything else I have tried has had drawbacks too.
3) The keyboard is light weight, as are the keys, for heavy typing work, this would be a drawback to me, although I am reluctant to say that this is a huge problem, as the overall feel is rather comfortable

Buen y muy útil teclado por el mouse integrado. Es en idioma Inglés sin Ñ.

Reviewed in Mexico on July 11, 2021

Size: Pack of 1Verified Purchase

Es un teclado muy cómodo y resistente que me ha prestado muy buen servicio desde que lo compré.
Este es un teclado de reemplazo para otro del mismo modelo (pero en idioma español) que tuve funcionando por años.
Teclas muy resistentes al desgaste y a diferencia de otros modelos, las teclas son suaves y no hacen demasiado ruido. El mouse es adecuado y una bendición para aquellos usos en los que no se requiere mucha precisión para el puntero y hay más énfasis en no usar varios dispositivos independientes.
A muchos no les agrada la tecla Enter de tamaño reducido, pero este tipo de tamaño de tecla es muy común en Laptops, por lo que los que estén acostumbrados a ello no tendrán problema.
No tiene soportes para elevar la inclinación, por lo que se recomienda para aquellas mesas que tienen una parte para el teclado más baja que el resto.
No es un teclado para videojuegos, por lo que si se usa con ese fin, habrá algunos problemas de tiempo de respuesta.
La vida útil de las batería con este teclado es excelente, aún si uno se olvida de apagarlo.

タイトルの通り。届いた商品パッケージには確かにK400と書かれているがキー配列がWEBの商品写真と異なる。
実際に届いたK400のパッケージのキー配列はK400rと同じ様だ。
具体的にはF1-F12キーに別のキーが割り当てられている、上部のホットキーの割り当てキーがWEBの商品写真と異なる。
写真を追加したので詳しくはそちらを参照して欲しい。

少し調べたところ、どうやらK400には仕様の違う初期型と後期型がある様だ。
初期型がWEBの商品写真のキー配列。F1-F12キーがそのまま使える。
後期型がK400rのキー配列。F1-F12キーはFNキーと当時押しが必要。
F1-F12キーがFNキーと同時押しする必要があるK400plusやK400rが嫌でこの商品が欲しい場合は注意。
私はこの点を期待して買ったのに意味が無く返品申請した。
買う前に販売業者にキー配列を問い合わせする事をオススメする。

This is the second one of these I have bought. The first was for the TV and it as worked for years. Easy to operate from my lap. This one I bought to bring with me when I am on the go with my Raspberry Pi 4B. It works out of the box with it. A nice size keyboard for adult sized fingers and an easy to use touchpad.
