Review: Compact, Powerful, and Surprisingly Quiet – Perfect for Detail Work! - The Bosch GEX 12V-125 is hands down one of the best sanders I’ve ever used. I was skeptical about how much power a 12V tool could deliver, but this little machine seriously impressed me. It’s compact, lightweight, and incredibly easy to handle—perfect for working in tight spots or for extended use without fatigue. Despite its size, it delivers smooth and consistent sanding performance. Dust collection is also very effective when paired with a vacuum, keeping the workspace clean. I love how quiet it is compared to larger models—it doesn’t feel like I’m waking up the neighborhood every time I use it. Battery life is solid, and with a spare 12V battery, I can get through most of my projects without interruption. If you're already in the Bosch 12V ecosystem, this is a no-brainer. Excellent build quality, great ergonomics, and ideal for woodworking, refinishing furniture, or any precision sanding work. Highly recommended for both DIYers and pros!
