It works great until it doesn’t. I’ve had this for 7 months and the mouse suddenly stopped working.The keyboard is actually pretty nice. I like the way the keys feel, it's very responsive.I haven't used it much though, because my main need here was for a good mouse. Lost my last one and got this to replace it because I figured they're all the same right?No.Single worst mouse I've ever used. Keeps slipping out of my hand, super picky about which surfaces it'll work on, it's just the worst. I'll definitely be replacing it, as soon as I'm able to.The keyboard is great, not to big but still has 10 key on the right. Keys are easy to read and responsive. The mouse on the other hand often disappears or floats away on its own. the pointer is not extremely accurate. It is very frustrating. I have debated returning the whole thing but I really do like the keyboard so I will probably go buy a better mouse and not use this one. It works like a mouse from long ago when you had to have a mouse pad to make the thing work, only even a mouse pad does not improve this ones effectiveness.I like the size of the keyboard and the smoothness as quietness of the mouse. The keyboard I first received had a malfunction and a new one was sent immediately, before I even sent the damaged one back. So that’s plus!I’m not crazy about the Size of the backspace button…smaller than I’m used to. Also the location of the delete button (right next to backspace). Just takes some getting used to. Also, there is a backspace like button (a back arrow) on the number pad side where I’m used to the dash being, so I’m always backspacing when I mean to use a dash.The mouse does not move right away. Sometimes it needs a tap or two on the desk to wake it up.Nice design and works great. I have not used it for gaming so no rating for that. Great price!This combo is a good set for people on a budget. The mouse does not have any drifting issues and seems to be accurate.I like how the mouse has different colors for the dpi setting you change to. The lighting on the mouse does cycle the different colors. The clicks feel solid and there have been no issues with any of the buttons or scroll wheel. You can see the red laser from the bottom through the lighting diffuser on top.The keyboard has not had any problems either. The rgb lights do not cycle as it seems like they are static but you can change the brightness. I did not realize until I opened the box that this keyboard has a United Kingdom setup, meaning that the enter button is larger than your normal United States setup so beware it may take some time to get used to if you are not used to it. The keyboard buttons are very quiet.Overall, I would recommend this mouse and keyboard combo if you need a set and don't mind the quirks of the key layout or the lighting being static.I got this keyboard and mouse for my son they are a nice addition to have for gaming the mouse is so user friendly easy to maneuver around and lighted so it's fun and easy to use at night to see what you're doing I wanted to try the keyboard out although I like the one, I already have this one is very quiet. For the price I think this is a great set to give or have for gaming I just think the keyboard could be a little more user friendly like the mouse.
