easily via Bluetooth. My work area contains an iMac, a Macbook Pro, and iOS devices. Photo shows other devices to give some idea of the proportions of the K780.

One of my tests was to run my fingertips over the keys. With most keyboards, you get that slight clicking noise from the play in the keys. Not so with the K780. The keys are firm in their positions. I found that for my typing style this makes for very confident and precise touch typing.

Problem: I have had a hard time connecting at all to Mac OS Sierra (10.12.3) via Bluetooth, The K780 doesn't even show up as an option in the Bluetooth setup screen, but the Unifying wireless works perfectly even on a 10 y.o. iMac running Snow Leopard (10.6.8). However, I have not been able to keep that Unifying connection to my iMac working when I enabled Bluetooth to connect to an iPad. Upon further post-purchase research, I discovered that there are known Bluetooth issues with Sierra. None of these cropped up in the reviews I read here; in fact, the opposite. Other than that, I want to love this keyboard and am still giving it 4 solid stars because it looks and feels great and absolutely works as advertised in Unifying mode. I hope to bump my review to 5 full stars if I can find a fix for this issue with Sierra. In fairness to Logitech, I believe that this is a Mac issue, not a problem per se with the keyboard.

我在考虑和试用了Logitech系列中的几款机型之后选购了这款键盘。 我因为它的重量和形状购买卖了它（这是一个非常好看的键盘），非常小的按键音（我将在录音室使用）和很好的性能（所以我认为）通过蓝牙可以轻松连接到多个设备。 我的工作区域包含iMac，Macbook Pro和iOS设备。 照片显示其他设备，来了解K780比例的一些想法。

我其中的一个测试是用我的指尖触键。 对于大多数键盘，您可以从按键中听到或大或小的咔哒声。 K780不是这样的。 他们的主要位置很牢固。 我发现，对于我的打字风格，这使我非常自信和准确的去触摸去打字。

问题：我很难通过蓝牙连接到Mac OS Sierra（10.12.3），K780甚至不会在蓝牙设置屏幕中显示这一个选项，但统一无线即使在 10 y.o. iMac运行Snow Leopard也很完美（10.6.8 iMac） 。 但是，当我启用蓝牙连接到iPad时，我无法保持统与我的iMac统一连接。 经过进一步购买后研究，我发现Sierra已经知道了蓝牙问题。 我在这里阅读的评论中没有一个人指出; 其实恰恰相反。 除此之外，我想我喜欢这个键盘，我仍然坚定地给它4颗星星，因为它的外观和感觉都很棒，绝对适用于统一模式下的广告。 如果我能找到一个关于这个问题的解决方案，我相信我的评论能达到5颗满星。公平地讲 ，对于 Logitech来说，我认为这是Mac的一个问题，并不是键盘本身的问题。

tly switch between devices. Bonus that it holds the devices too. I use the USB receiver with my Win10 laptop (on a desk stand next to a second monitor). I put my Iphone and Ipad in the keyboard rack. With the touch of a button I switch instantly between the three devices. Fast texting and writing to calendar on I devices while working on laptop etc.

Keyboard is heavier than most, which people equate to quality. For me maybe it makes it more stable.

Batteries are included, two AAAs.

Usb receiver storage next to batteries.

Connect your other Logitech devices to this usb receiver with the Unifying program at Logitech site. Amazon won't let me give you the link. I combined an old mouse and it all works on one usb receiver.

这款产品是完美的。 我想要的按键（超短距离）。 我拿着它，按键既好用声音又小。 也使我在打字时不会抓住其他键的角落快速的打字。 删除按钮是必要的（和苹果一样）。

我一直在等待一个可以立即在设备之间切换的键盘。 它拥有奖金的设备。 我的Win10笔记本电脑使用USB接收器（在第二台显示器旁边的桌面上）。 我将Iphone和Ipad放在键盘机架上。 通过按下按钮，我可以立即在三个设备之间切换。 在笔记本电脑上工作时，可以在I设备上快速发短信和写日历。

the numeric keypad a lot, so I wanted this model. It took me about a half hour to get used to it because the shift key, for some reason, feels like it's in a different position then my prior board. I really like the keyboard as it sits flat, is small and takes up a lot less room then my other keyboard. I think I can compare this to the Apple keyboard. It also reminds me of the old PC Jr. keyboard that was often referred to as a chicklet keyboard. It is easy to use and it has that click feel that I like.

我的妻子买了一个像这样的Logitech键盘，但没有数字键盘。 她在本地购买的，比我在亚马逊上买的贵一些。 我试用过她的键盘，我很喜欢。 它比以前的Logitech键盘小得多，而且很平稳。 我经常使用数字键盘，所以我想要这款产品。 我花了大约半个小时才习惯它，因为转换键，由于某种原因，感觉和我之前的键盘有所不同。 我真的很喜欢平稳的键盘，很小，比我其他的键盘占用的空间少。 我想我可以把它与苹果键盘进行比较。 它也提醒我想起我的旧PC Jr.键盘，通常被称为小插入键盘。 它很容易使用，它具有我喜欢的那种点击感。

Anyways set up is dead simple.
Follow the instructions on the box and you'll be fine, just remember to use the right process for either MacOS or Windows etc.

The keys have a very, very solid feel to them. They feel leaps and bounds better to me than the action you get on a macbook pro keyboard pre 2016 or the magic keyboard version 1. Just less squish and more satisfying.

Holy smokes they're quiet too, it's like the ninja of keyboards.

The circular keys were really easy to get used to, and to be frank they look so much nicer from an aesthetic point of view in my opinion. Very typewriter-esque.

Pairing with the unifying dongle was great because I also bought a Logitech MX Master mouse, it simply required I plug both dongles in at first.
Eventually the software (for the love of god just install Options, it's amazing) recognized I had two dongles and asked if I'd like to remove one from my mix. Easy to follow steps later and I was there.

There's a fair amount of travel for such a low profile keyboard on the keys, nothing crazy but enough to really feel like I got ish done when I finish banging out an email.

Most importantly, switching between machines that I control with this is a breeze. Once you're done pairing you literally just hit the button on the keyboard for the device you'd like to control and you're done.

I game on a PC and I work on a Macbook Pro 2016, and this thing does it all.

I high reccomend installing the options software, so you can remap the FN keys and change their behavior.

Are you one of those heathens that wants the FN keys to automatically require you hold FN to do volume up and down? There's a setting for that.
Do you want to map the home button on Windows 10 to TaskView (which I love)? Go for it, in Options.

You can even turn on application specific mapping of buttons and have the mappable buttons do different things depending on what app you're focused on at the moment. I've done this with Excel and a few games.

Lastly even if you don't want to use this to control a phone or tablet, the little tray is one of the coolest things ever, because you simply just "dock" your phone or tab there. I use it with my LG G6 and it's just superb.

Over all if you're thinking about getting this keyboard stop thinking and start doing.

Even if you don't have more than one device, and don't plan to use its switching capabilities, it's just a fantastic piece of kit that's really one of a kind and works really well.

这是我使用过的最好的键盘之一。

首先包装本身，我不是罗技的粉丝，而是从盒子到产品的美学就是完美，太棒了。非常现代简约的感觉。就像这个键盘是一个大家庭...

无论如何设置都非常简单。

按照盒子上的说明，你会很好安装，只要记住使用正确的进程为MacOS或Windows等。

按键有非常非常坚实的感觉。对于我来说，它们比在2016年前的macbook pro键盘或魔术键盘版本1上获得的动作更好。

它们也很安静，就像键盘的忍者。

圆形键真的很容易习惯，坦白说，从我的观点来看，它们从审美的角度看起来更好。打字机非常舒服

与统一的加密狗配对是很不错的设计，因为我也买了一个罗技MX Master鼠标，它只是要求我先插入两个加密狗。

最终软件（这只是安装选项，比较容易安装）识别出我有两个加密狗，并问我是否要从我的混合中删除。很容易跟随步骤进行操作。

最重要的是，我用这个键盘控制机器之间的切换是轻而易举的事情。一旦你完成配对，你的字面上只要按下键盘上的按钮，你想要控制的设备，就完成了。

我在一台电脑上玩游戏，我在Macbook Pro 2016上工作，这些都很容易完成。

我高度推荐安装选项软件，因此您可以重新映射FN键并更改其行为。

您是否想要FN键自动按您要求按住FN键进行音量调节？有一个设置。

你想将Windows 10上的主页按钮映射到TaskView（我喜欢）吗？在选项中找到它就可以了。

您甚至可以设置打开应用程序特定的按钮映射，并且可映射的按钮根据您目前所关注的应用程序而做不同的事情。我已经将这项功能运用在Excel和几款游戏上了。

最后，即使您不想使用它来控制手机或平板电脑，小托盘也是最酷的东西之一，因为您只需“停靠”您的手机里的标签页。它能够与我的LG G6搭配使用，这是一流的。

总而言之，这款键盘简单易用，不需要你过多的思考怎么使用。

即使您没有多台设备，也不打算使用其切换功能，它也是一个非常棒的套件，真的是一种非常棒的工具，效果非常好。
