It should last, but could be much better.
Color: Black
The keys are quiet and the keyboard should last a long time. Being a flat keyboard, I find myself hitting two keys at the same time frequently, and prefer the style with raised, tapered keys. The mouse times out and needs to be woke up by right clicking, but other times seems to lose connectivity entirely. Overall, I wish for something better

Great low price option for wireless keyboard
Color: Black
I’ve been using this ergonomic wireless keyboard and mouse for a bit now, and I’m honestly really happy with it. It’s super lightweight, and setup was as simple as plugging in the USB receiver; everything worked right away without me having to mess with any settings.
The keyboard feels great to type on. The keys are soft and quiet, and the adjustable tilt makes a noticeable difference for my wrists during longer work stretches. I also like having the full number pad and the shortcut keys, little things, but they make my day-to-day work smoother.
The mouse is comfortable and easy to control, and I haven’t had any issues with the wireless connection at all. No lag, no random disconnects. Battery life has also been impressive so far.
Overall, it’s easy to use, comfortable, and does exactly what I need it to. I’m definitely happy with the purchase.

Exactly what you need
Color: Black
This is a perfect and conformist up. Excellent spacing between keys and the number section is comfortable to use because it is large enough to make it a comfortable set up
No instamtions issues and no communication issues with it and my Lenovo Think Pad

Just what I needed!!
Color: Black
The wireless keyboard & mouse is being used with an aging laptop - the laptop's keyboard & touchpad were almost unusable, but the laptop itself (with a few minor upgrades) performed well considering its age. The keyboard uses one (1) AAA battery, is full size, and operates smoothly with no 'hiccups' or annoyances; the mouse uses one (1) AA battery, has auto-sleep built-in that kick in after approx 5 minutes of non-use, that takes a bit of getting use to bc you have to left or right click to wake it before it will respond to any motion - that's not really a 'con' bc that function could potentially extend battery life. It's an inexpensive way to get a new & functional input interface for your computer.
