Buying Guide
- Power vs. weight: Higher wattage polishes can remove defects faster but may be heavier. Balance your tolerance for heft with the task length you anticipate.

- Ergonomics and handles: Detachable or multiple grip options (D-handle, side handle) reduce fatigue on long sessions. Ensure the design fits your hand size and typical grip.
- Build quality and durability: Look for ball-bearing constructions, robust gearcases, and heat management features to sustain consistent results.
- Cord length and mobility: Longer cords improve reach for large vehicles and boats; consider models offering upgraded cords or cordless alternatives if applicable.
- Accessories compatibility: Confirm compatible backing plates, pads, and locking mechanisms to avoid fit issues between models.
- Safety features: Features like a safety lock or dead-man switch can prevent accidental starts during setup or adjustments.
