I'm happy with this DJ mixer. Makes your vinyls sound better than ever. EQ is musical to my ears, unlike on some other entry level DJ mixers. Also Isolator is useful for tuning bass and high freq content to your liking. EQ and Isolator have different tuning points, so you can, for instance, boost and cut low frequences at the same time and have different sounds sculpted out. Nothing sounds harsh or exaggerated to me, all controls are useful, depending on the material played.
