Works great.
Color: Silver, Style: 1-Pack
I have to edit my review: the mouse itself is still working fine, I happened to get a bad batch of Kirkland batteries! I changed out the batteries with a different brand and the mouse is working perfectly!! Didn't last very long, have only had it 3 1/2 months and it has stopped working.

Fantastic keyboard
I did a lot of research before choosing this keyboard, and man am I glad I got it! The split is great, very comfortable. The arch is minimal, but it does the job. I also really like this scissor-switch technology, no more backspacing to fix a key that didn't register the first time! The built-in wrist rest is also really nice. I type a lot for work, and at a rate of 55 WPM. The keyboard gives just the right amount of feedback, and the keys are not mushy at all.
It's also a very good looking keyboard, and is very responsive. I have heard some people mention (not just on this keyboard) that they have some lag/delay with their typing. I would bet the farm that they have plugged the receiver into a USB hub. If you're going to do that, then get yourself a USB extension cable, because the hub will cause interference with ANY wireless dongle you plug into it. Just a foot or so of distance from the hub will alleviate that. I found that out with my prior Logitech keyboard, after lots of searching around for what the cause could be.
The ONLY thing I would improve is fairly minor: It does not have dedicated keys for Page Up/Down, Home, or End. You need to hold down the function key and use the corresponding arrow key for those functions. Not even remotely a deal breaker, this keyboard is fantastic in every other aspect.

Great Keyboard & Excellent Customer Service
I’ve been using this keyboard for almost 3 years and it has worked great for me the entire time. Comfortable, reliable, and perfect for long hours of work.
The customer service was also great — very responsive, helpful, and professional throughout the process.
Very happy with the product overall and would definitely recommend it.

Soft keyboards ( updated)
The keys fell off very easily after only 2.5 months of use. It is a nice and smooth keyboard. I like it, but it didn't last even 3 months. I am trying to get it repaired by them since it was so recent that I got it- I will update this review later once I hear from the manufacturer.
This is an update to my original post. I am extremely impressed with the quality of customer service and how fast they addressed my concerns regarding the product and they honestly back up their product. Not only did they respond fast, but they also replace my keyboard. Not just fix it, replaced the whole thing and it is also backed by their manufacturer warranty. I’m so happy and love that I get to have my keyboard back to use for hopefully a lot longer this time. It truly is a comfort keyboard and I love how smooth the keys feel when typing for long periods of time. Thanks guys for the prompt response!
Today 3/27/2026 I received my brand new keyboard to replaced the one with the broken keys and I’m so happy to it back again and fully working thanks guys for the great customer service. Truly appreciate it.
