Dream Machines DM6 Holey S Gaming Mouse Review
 

We have used quite a bit of mice with Pixart 3389 sensor and even some from Dream Machines (DM1 FPS, DM2 Supreme) and we knew what to expect in terms of tracking. The choice DM made to use a rubberized layer on the entire top cover of the DM6 Holey S is great for comfort and grip, but it will pick up skin oils and lint quite easily, which are quite difficult to remove after a while.
