Keyboard colors are nice. That's good because you can't change colors or brightness on either the keyboard or the mouse (the mouse will flash color based on the DPI level set, then revert to the normal color pattern). Also, my CAPS button went out after about 2 months. I don't know why, but the keys are very high. I'm talking an inch up or up. Too high for normal use. It's like your fingers are jumping over mountain tops and I have fat fingers so I have a hard time typing fast. The mouse works perfectly. I like being able to switch between DPIs on the fly without having to go into mouse settings. The 2 thumb buttons work fine and are in a good place. The funny thing about these Chinese products is that they both appear to be wired only, but there is a sticker on the mouse that says 'Wireless' lol. The keyboard has a regular black cable while the mouse has a blue braided cable. Both are too short if the USB connection to the PC is on the floor. I recommend getting a USB hub or running it through your monitor. All in all not recommended. These are silicon prices or cheaper combination products that offer more. I would have received a refund but I really needed it as I had my computer reassembled the same day. The keyboard sucks because it's like jumping over the Himalayas, but the mouse is pretty good.
