Gemini started out as a smaller DJ equipment company that had a difficult time finding their place in the DJ community. Much of their equipment was not on par with the quality of the top contenders, but prices reflected this. Since then, they have vastly improved the quality of their devices while still retaining a good selling point.
The Gemini CDJ-650 is a prime example of this. They look very similar to Pioneer’s offerings but at a fraction of the cost, and build quality is surprisingly very good. The 650 also offers a tilted readout display that you would only find on Pioneer’s CDJ-2000.
