(Tested with oscillating-tool attachment BDCMTO)
The Matrix is the only tool with the pistol-grip shape of a drill/driver. It's a fine configuration while sanding, but the offset handle makes vertical plunge-cutting very uncomfortable. While it has the same easy-to-use blade-change lever as the Porter-Cable, the hand-numbing vibration was worse than any other tool, and it underperformed in both the sanding and recharge tests.
