    Both keyboard and mouse work seamlessly. Easy to connect, no disconnect for bluetooth, battery life has lasted 3 months and counting. For the keyboard i thought it was auto-on but alas there is a power switch on the side (i was going to return until i found this). Mouse is ergonmically comfortable and has auto-scroll function as well as customizable buttons. Honestly for the price it’s worth it.

    This is the sweet spot for me with business and home keyboards and mouse combo. I do not like the “ergo” keyboards that are split or curved, and this one is only slightly raised in the center to make the hand transition easier. No, it’s no mechanical keyboard, and no trackpad (thankfully). Simple connection, 10-key, functional keyboard with a decent wrist rest. Mouse is good, though I use the logi ergo vertical one preferrably

    This keyboard and mouse combo is one of the best combo you can get with the same amount of budget. The combo provides both USB receiver and Bluetooth for easy connection to your computer. Both ways are extremely simple and quick. You can also make some adjustments to the keyboard and mouse through their app according to your own needs. The mouse gives a very comfortable grip in which the shape fits snugly into the palm. The best part of the combo is that the keyboard has really soft and quiet keys unlike any other keyboards in the market. It keeps those annoying typing noises away.

    Instructions for USB stub are confusing, had to install Keyboard and Mouse through Logi software since Bluetooth in Windows 11 kept reporting errors.

    Everything was fine until I started browsing…. when using the Moused Wheel, the screen kept scrolling forward and BACKWARD when I was scrolling FORWARD — it’s WAY TO LOOSE!

    I’ve bought 2 of these. I gave the first one away when I moved overseas. I work from home and use it to switch between my personal PC and my work PC. I sometimes use the third pairing for my tablet.
    My personal PC is a pretty old MacBook, which can be skittish about Bluetooth. These devices always connect quickly without hassles by either the included unifying receiver dongle or Bluetooth. Switching between devices is essentially instantaneous. Both are reasonably ergonomic. The build quality is decent, and not cheap feeling.

    The keyboard has an old-school feel that I like. But someone raised on newer ones may not care for the travel distance of the keys. And some people may feel that typing is too noisy. As I say, it’s old-school style. There is no Print Screen (Prt Scr) key, which is the default for some screen capture programs like Greenshot. (But you can change it to a F key or some shortcut.) Battery life is good, and you can extend it if you remember to switch them off at night.

    In short, good quality, ergonomic, connectivity is quick and easy.

    First the good. I like the soft press of the keys, the nicely arched keyboard, the functionality of the buttons, and the ability to switch between devices. These all make this a fantastic keyboard for me. The hand rest is very comfortable as well and I like the feel of the material. It is a unique kind of rubber mesh with some kind of foam padding underneath and I find it very pleasant to rest my palms on.

    Condition of the item was great. No blemishes that I found despite being renewed. Seemed to come with everything required, batteries and packaging looked more or less original. No complaints. One odd thing is that there were two USB devices in the package and one did not seem to work. I can’t be sure if it just wasn’t the original so it wasn’t paired, or if it was non functional, but this led to some of the frustrations in setup.

    Setup was bafflingly difficult. A lot of that was because of the above, having two different USB devices, one likely being defective, but I was about to give up and send it back. No manual was included with mine, so I just tried to follow the quick guide and it was very difficult to understand.

    I won’t go through all the details, but basically, I used the USB device that was either defective or not paired, so I couldn’t get it to talk through that. Then I got the mouse and keyboard connected through bluetooth (I had to use another mouse and keyboard to accomplish this) but the keyboard kept acting strangely, getting stuck on certain keys. Once I found the other USB device (one was in a package in the box, the other was inserted into its storage spot in the mouse) setup worked ok. Definitely suggest getting the logi options+ app first if you have another keyboard and mouse, as it gave me a lot more feedback as to what was connected.

    Finally, only other small gripe is that as much as I like the wrist support padding with the foam/rubber mesh, I’m afraid that the little mesh holes are going to get filled up with dead skin that rubs off and other schmutz. So far stuff has been easy enough to brush off, but I think it will, at the very least, require some maintenance.

    The media could not be loaded.

     Lots of customizations and mouse gestures that you can tweak with Logitech app. Great value product and comfort

    Unfortunately, I belive this was a refurbished or new unit not in original packing, and it has issues where the key board stops working. At first, not too bad, I have to disconnect the batteries and reconnect them. That was happening about once every 2 weeks, now it happens about once every 2-3 hours. Also, in the last day the ‘numbers’ keypad on the right side of the keyboard is no longer working. Pushing the number lock key ‘on’ and ‘off’, disconnect battery’s, still no difference. Have had this for only 7 months, usually get 3 years out of a keyboard. Time for a new one.
