Our Verdict

J-Tech Digital V628X

Kensington SlimBlade Trackball

The J-Tech Digital V628X and the Kensington SlimBlade Trackball are two very different mice, but they're both designed for office and productivity use. However, the SlimBlade is a trackball mouse that performs better overall. It feels significantly better-built and more comfortable to use, and its sensor is much more consistent. On the other hand, the J-Tech is a vertically oriented mouse with an adjustable angle.
