My son asked for a Razer mechanical keyboard for his birthday when he was 14, and after I was convinced that he *Needed* it, got him another piece every year, until he went to college. I have since gotten myself a chroma, not entirely necessary, but I like it. I have not, however, gotten all the accessories.This mouse is being used on our family computer. It was very easy to set up. and made it more enjoyable as soon as it was plugged it. We have a logitech gaming keyboard, and some razer headphones (which will probably wind up in Our son''s hands eventually). I would say our needs are modest by comparison (and, in facty, they are) but his sister moved back home a few months ago, and having left everything she owned behind. os now using this computer.The mouse is precise and cycles through 16.4 million colors without programming. I am not sure if we will be able to synch the equipment since it is all from different manufacturers, but given that each piece cost 1/2-1/3 of what I paid for my son's equipment, I can live with that.Kinesis says that macrtos can be programmed. That is not something I have needed to do, but my daughter very well may after she takes over the computer in our living room.Given that I haven't tested the limits on thios mouse, I can say that it is easy to set up and easy to use, produces a simple cycling light display without programming, is not just useable, but more accurate than the mouse we had been using,. and is a great buy if you are someone you know are looking for a little color without a large expenditure.
