It is a nice idea

Very nice, but disappointing when connecting. It was sensitive to being shielded by metal

Quality product

Quick setup, smooth motion, and responsive keys! I love that I can use this with multiple laptops and do not need the dongle beyond initial setup. The rechargeable battery is a plus!

Good Keyboard and Mouse

The keyboard has very smooth action and quiet key clicks. Mouse works good, and smooth. It is sensitive to the surface type of the mouse pad so buy a good one. They both have good battery life on a charge, and no more changing batteries. Like the pair and recommend.

Not happy with the purchase

Keyboard does not have cap lock light - I didn't pay attention when I bought so it's my bad. But then the mouse stopped working after 1 month out of the blue this morning when am working from home.i had to rush to Staples to buy another set of USB keyboard and mouse in order to continue working from home. Then I logged on to find out the item cannot be returned - maybe it just passed the 30-day return window?? Super frustrating.

Good cable by third party supplier

This is a third party product. I had to purchase because the original cable is not compatible with my laptop. It's good but you can't monitor the shipping status. Therefore 1less star.

Solid daily driver for both mouse and keyboard

Upgraded from the Microsoft Surface Pro keyboard purely for the sole fact of this keyboard and mice having built-in device switching buttons making this significantly easier to swap devices quickly. The feel of this keyboard is similar without the quite so much premium feel of the other. Added benefit of the included dongle is the ability to access BIOS settings without the needs of an addition keyboard. Overall well worth the value at ~$50

Sturdy Touch & Feel / Ready to go out of the box

Wonderful texture and touch for both the keyboard and mouse. Worked seamlessly out of the box without any setup. Use primarily with my docked laptop and external monitor. Light weight mouse, but quick, firm response with minimal input/movement. Full keyboard that is both compact and sturdy. Very happy with purchase. Plan to use for many years.

Very solid and functional.

This is a very good combo. Could be connected to 3 devices. The keyboard is compact, but without losing functionality! It looks very solid and has good key travel. The mouse is more suitable for people with average hands. It is very good and pleasant to work with.

Thank you for sponsoring DUCATI.

Keys stick on sometimes while I am typing. CapsLock key is too easy to accidentally hit. Last Lenovo keyboard similar to this one died completely in two years.

Keyboard and mouse that works well

It's a good Keyboard and Mouse. Thought it was Bluetooth but it has the dongle which takes up a USB port that would be well used for something else.

Solid dock companion

I leave this combo pluged into the usb on my dock. The keyboard and mouse have a moderate response time for most work tasks. I still use a more sensitive mouse for freehand drawing or creative tasks. Good value. Keyboard keys feel more solid than the non-pro option. Takes a little more desk space also than the non-pro keyboard but doesn't unintentionally slide around.

Wireless Keyboard and Mouse Lenovo

Wireless Keyboard and Mouse were pretty good. I prefer a more full body mouse and found this form factor a bit too low profile. The keyboard is standard as well. I wish both has the option of USB charging instead of batteries but it's not a major issue.

Bon achat

Le clavier est très plaisant à utiliser. Touches assez distancées, fini agréable sous les doigts, peu bruyant. La souris fonctionne bien, mais elle est un peu grosse pour de petites mains.

Lenovo Professional Wireless Combo Keyboard & Mous

By GWH121957

I'm an old guy, set in his ways and I was reluctant to 'cut the cord' of my old reliable keyboard and mouse. This product is a game changer and it keeps the cords off my desk. The keyboard is a huge upgrade from the 10 year old model it replaces....the keys work so much better. And the mouse is way more sensitive. Overall, this is a definite improvement over what it replaces...I just wish I had made the move to wireless years earlier. IMO, 5 stars to this item.

Because efficiency and sustainability meet in the Lenovo Professional Wireless Rechargeable Combo Keyboard and Mouse, this set is a game-changer for both professional and personal use. The full-size keyboard, equipped with quiet membrane keys, offers an elevated typing experience akin to a laptop keyboard, as noted by numerous user reviews. This feature, coupled with a robust wireless range, ensures seamless operation whether you're at your desk or lounging on your couch.

The mouse, meticulously crafted from bio-rubber, provides all-day comfort and precision with its impressive 4,000 DPI sensor. However, it's worth noting that some users have found the mouse clicks to be louder than expected.

One of the standout features of this combo set is its impressive battery life. The keyboard charges in approximately two hours via the supplied USB cable and can be used while charging. A single charge can power your work for an entire week, even for those working remotely for 8-11 hours a day.

In line with Lenovo's commitment to the environment, both the keyboard and mouse are made from 65% recycled material. This eco-friendly design not only reduces your carbon footprint but also ensures you're investing in a product that values sustainability.

In conclusion, the Lenovo Professional Wireless Rechargeable Combo Keyboard and Mouse is more than just a tool for productivity; it's a testament to innovative design, environmental consciousness, and user-centric functionality.
