### ⭐⭐⭐⭐⭐ Review
*by I***C on 4 December 2023*

Bought this to replace my old broken simpad and I was totally blown away. The quality and features are that of something even twice this price, and the tunability is incredibly helpful. Only gripe is that this thing only takes magnetic switches so if you have a whole bunch of cherry ones sitting around that you want to swap into this, tough luck. I think thats a very irrelevant thing to most people though, me included, since the ones that come with it are great. Solid 10/10
