AI Verdict
This full-size membrane keyboard with Bluetooth and USB Unifying Receiver lets you switch between three devices, holding a phone or tablet in its integrated stand.
This keyboard is a strong fit for anyone juggling multiple devices at their desk. Its ability to switch between three connections and the integrated device stand directly address the clutter and inefficiency of using separate keyboards for each device. The full-size layout also means no compromise on typing experience for productivity tasks.
If multi-device switching isn't a priority, look for a keyboard with adjustable tilt feet and dedicated media keys for better ergonomics and convenience.

The membrane keys are described as quiet and comfortable with a low profile, though the circular keycaps and small arrow keys require adjustment.
Offers both Bluetooth and a Unifying Receiver, providing flexibility, but some users report occasional Bluetooth lag or initial connection difficulties.
The keyboard does not have any backlighting, which is a significant omission for use in low-light conditions.
Users consistently describe the keyboard as having a solid build and a substantial 1.92-pound weight, contributing to its stability on a desk.
Best For

- The integrated stand's fixed angle might not be ergonomically ideal for everyone, potentially causing neck strain during prolonged use.

What Buyers Say
The K780's standout feature is its seamless multi-device switching, allowing users to jump between a computer, phone, and tablet with a single button press, which many find to be a 'game-changer' for productivity. The integrated stand is frequently praised for holding devices securely and at a convenient angle. While the membrane keys are generally considered quiet and comfortable for typing, the lack of backlighting is a common point of contention. Its substantial 1.92-pound weight contributes to a feeling of durability but makes it less ideal for portability.
“Dude, this keyboard is a lifesaver for my messy desk, I can finally type on my iPad without balancing it on a stack of books, but seriously, why no Caps Lock light?!”
Common Praise
- Easy and quick switching between up to three connected devices
- Integrated stand securely holds phones and tablets, reducing desk clutter
- Keys are quiet and provide a comfortable typing experience
- Exceptional battery life, with some users reporting years of use on original AAA batteries
- Solid and durable build quality, feeling substantial on the desk
- Full-size layout with a number pad is beneficial for productivity
Common Complaints
- Absence of backlighting makes typing in dim environments challenging
- F-keys default to media functions, requiring 'Fn' for standard F-key use, which can be frustrating
- Circular keycaps and small, pill-shaped arrow keys take time to adapt to
- No indicator light for Caps Lock or Num Lock
- The 1.92-pound weight is not ideal for frequent transport
- Occasional Bluetooth lag or initial connection issues reported by some users
Ownership Tips
- The long battery life means you'll rarely think about changing the two AAA batteries, even after years of daily use.
- You'll likely need to adjust the F-key settings in Logitech Options software if you use F1-F12 regularly, as they default to media controls.
- The integrated stand is super handy, but if your phone case is thick, it might not sit perfectly or at the best viewing angle.
- The keyboard's weight, while making it feel sturdy, means it's really a 'desk keyboard' and not one you'll want to toss in a backpack often.
- The rounded keys and small arrow keys might slow down your typing speed initially until muscle memory kicks in.

Buying Guide
When you're looking at keyboards like this, think about how many devices you actually use at your desk. If you're constantly switching between your computer, phone, and tablet, a multi-device keyboard can seriously streamline your workflow. Also, consider where you'll be using it; a heavier keyboard like this is meant to stay put, not travel. Don't forget about the type of keys – membrane keys are generally quieter but won't give you the tactile feedback of mechanical switches.
Multi-device wireless (Bluetooth + USB Unifying Receiver)
This means you can connect the keyboard to up to three different gadgets, like your desktop, laptop, and phone, and switch between them instantly. It's like having one remote for all your TVs, but for typing.
Membrane type
This refers to the mechanism under each key. Membrane keyboards are typically quieter and softer to type on compared to clicky mechanical keyboards. If you share a workspace or prefer a silent typing experience, this is a plus.
Integrated phone and tablet stand
This built-in groove holds your mobile devices upright, turning your phone or tablet into a mini-monitor. It frees up desk space and puts your screen at a better viewing angle while you type on the full-size keyboard.
Alternatives
If you need a lighter keyboard for portability, search for models under 1 pound. For a more tactile typing experience, look for keyboards with mechanical switches.
