Love this keyboard. It helps me to switch between multiple devices with single click and be always on top of them. Round keys feels a bit strange at the very beginning, but once you get used to them nothing else can stand. Keyboard is a little bit heavy, but it is designed that way to be able to hold tablet or phone. I like the idea of having both layouts available: Apple and standard PC for Alt/Meta/Control/Com­mand. Idea of two protocols: unifying receiver and Bluetooth is outstanding.

I'm not sure how well this keyboard would work for a gaming keyboard. Ive tried several keyboards trying to find the right fit but all were really the same thing, some wired, wireless, backlit, mechanical keys and so on.

The round keys are great and the keystroke is short and responsive; I am a draftsman and use this keyboard daily, one thing I do like is the small area it takes up in my work space; I have not had any issues connecting with my tablet, phone and primarily used with my pc

None that I have found

The K780 is a great help for using your phone or tablet as a second screen alongside your laptop or PC. This single keyboard can switch among devices with a single button press, making it easy to deal with incoming texts, for example. We just wish it also had an integrated pointing device.

Easy to switch among mobile and desktop devices connected to same keyboard; Solid; sturdy design; Well-spaced keys are a pleasure to type on

Difficult to store wireless adapter; No integrated pointing device

In this day and age you are probably using anywhere from 2-4 devices on the daily. I can imagine one of those would at least be a PC and then a smartphone. Some might have multiple smartphones and even a tablet. Going from typing on your PC to your mobile device can definitely be a chore.

Keyboards , especially non-gaming ones, can be a little boring and one dimensional at times. The K780 wireless one from Logitech, however, cannot be described as such. It's designed not simply to work in conjunction with one's PC, but also pairs with smartphones and tablets too.

Silent keystroke; Quick device pairing; Solidly built

Circular key design not for everyone

If you've ever suffered texter's thumb, you might have wished for a full-sized wireless keyboard for your smartphone. Logitech has just that in the shape of the K780 Multi-Device Wireless Keyboard, and it goes beyond replacing the on-screen ‘board too: it'll not only stand your iPhone and iPad up in...

Three devices; one keyboard; Solid key-feel; Lengthy battery life

Keys aren't backlit; Software-only Caps Lock / Num Lock indicators; There are much cheaper wireless keyboards out there

Logitech has a penchant for designing multi-device peripherals for desk-dwellers who don't want to clutter their workspace. The MX Master mouse from 2015 was one of the finest examples of this, and the new K780 is a complementary addition.

Attractive build; Seamless device switching; Long battery life

Keys not backlit; Symbols are stickers; No Caps lock or Num lock indicators; Bluetooth less reliable than Logitech dongle

The Logitech K780 bluetooth keyboard pairs with a tablet, phone, and PC, at the same time, and can be easily switched between any of the three. Does this 3-in-1 keyboard[...]

Logitech certainly understands the keyboard game, and the K780 is a smooth unit to work with. Fingers don't need to press down too hard or far to register strokes (easy on fatigue), and the keys are able to handle 112+ wpm continual typing without any skips/misses, delays, or doubling-up.

Back in the day if you wanted to share one keyboard and one mouse between two computers, you had to use a clunky switch box that was connected to both devices. Today Bluetooth makes wires and stand alone switch boxes obsolete.

2 AAA batteries power the keyboard for up to 24 months; Comfortable to type on; No weird key layout; Easy switching between 3 paired devices
