At this price you can't expect top of the range
So where to start, the keyboard makes a horrible noise, I don't know where the blue switches come from but they are really not qualitative, the plastics are cheap as possible and the backlighting the same, the mouse is the height of the pack, it looks like a toy for a child with nothing inside, the colour inside is not even well distributed there are places where you can see through, I can't advise this product there are non-mechanical keyboards of much better quality same for the mice, the worst of the made in china clearly
