Battery life actually holds up through a full afternoon of trim work, and the lack of a cord makes it feel twice as maneuverable in those awkward ceiling spots. The delta shape fits perfectly into the tight corners I always struggled with before.

The delta pad gets into corners my other sander just can’t reach, and the cordless freedom means I’m not fighting an outlet in tight spots. It’s noticeably precise on trim work, and the dust collection keeps the mess manageable.

Battery life is a pleasant surprise — it held up through a full afternoon of trim work without needing a recharge. The cordless freedom really makes a difference when you're up on a ladder.
