Bests & Worsts Reviews from Amazon

I Ordered this package in spite of other reviewers warnings. Well I learned not to do that again. You do not know what you are going to get. You do not know what will work and what will not. I got the package and tried to pair the mouse and the key board with my mac pro lap-top that I bought in 2014. Mouse worked fine but the key board, I could not pair. I told this to amazon. They said they will replace it. Stay tuned. In hind sight I do not think saving $40 was worth this trouble.
