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.
