Summary
4.3 stars, 650 Amazon reviews. Users appreciate the StarlockPlus quick-change system for swapping pads without tools. The sealed micro-port dust collection is better than most cordless detail sanders. Compact design fits into tight spots. Some users note the 14,000 OPM fixed speed is a bit aggressive for very delicate work.
$60-$90 Amazon, Home Depot as of April 2026
