Prioritizing smoothness (rotation) makes fine work unstable... Prioritizing fineness (stability) makes large movements stressful... The EN・KAKU created this time is a balanced type. ⬜︎ About Bearings Compared to regular ceramic balls, the movement is smoother and improves operability, but on the other hand, a slight rubbing feel and sound will occur. Three high-precision NMB MinebeaMitsumi bearings (DDL-415X5ZZ) are used. It may feel a bit expensive, but the price includes the bearings and screws x 3. Users only need to prepare a 25mm trackball to use it. ⬜︎ Compatible Balls Compatible balls are Perixx 25mm balls. POM balls are also supported, but due to individual differences in size, if the sliding is poor during operation check, fine adjustment is required by loosening the center bearing. ⬜︎ Two Designs EN, which has a rounded shape and a soft, slightly cute impression. KAKU, which is solid and angular, with a cool impression.
