There are several things that members of the enthusiast community can agree on. The 2080 ti is a monster of a card, AMD Ryzen processors are the best thing AMD has produced maybe ever.  But, the one area that people are most opinionated must be peripherals. This is because peripherals are very subjective. What I like, you may not. What’s comfortable for me, may not be for you. But, in my humble opinion, your mouse is the most important part of your set up, hands down. The first peripheral review was back in 2016 and was of the Mad Catz R.A.T. Pro X. Up until that point, I had never personally used a Mad Catz product. However, I fell in love with the R.A.T. Pro X. So, when I was asked to look at the R.A.T. Pro S3, I was more than willing. So, let’s take a look at the R.A.T. Pro S3 and see how it holds up to the competition.
