I now use this keyboard daily. I've had it for several years (it may have changed since then). The mouse's left click wore out after 2-3 years but it was otherwise fine to use. Originally I purchased it for a cheap combo to use at my workstation at work, but after switching to work-from-home and now being a married man with kids and living in a small apartment, I use this keyboard simply because it's not terrible to type on while being reasonably quiet (the wife would constantly complain about my expensive, mechanical keyboards being noisy).

Anyway, not a terrible combo... probably one of the best (if not the best) to be had at this price point, for sure.

Had one for years, first "gaming" keyboard I could afford. Still my test keyboard when building new PCs. Nothing to write home about membrane keys but for this price it would be great for an adult buying for their kid to get into pc gaming.

Does it still have the issue where lighting is controlled by the scroll lock key, making it a serious pain to use with spreadsheets?

I had one of these years ago, had to look up a mod on YouTube to disable that and make the lighting always on.
