My wife purchased this for Christmas for me (after I chose it lol) but I finally got the chance to unbox and use it today. The keyboard is amazing, the switches are louder than a lot of others, but I prefer them that way. The mouse has a bit of heft to it so if you prefer a super light weight mouse this one might be a bit heavy, but again, that's how I prefer it. The driver software for the keyboard and mouse on their website work perfect for me and the keyboard lighting is fully customizable along with the mouse lighting and sensitivities.
One issue I'm having is trying to find the right driver for the headset, on the webpage it has multiple options and says to refer to your user manual to find out what chipset you have in your headset, but the manual nor the actual headset have a model number and these particular headphones aren't sold separately on their website to find out. That being said, they still work without it.
Note-All of the products worked for me without downloading drivers/software, but I suggest downloading the correct software so you can further customize your setup.
