The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Bosch GEX18V-5N draws the category's most polarized response. Expert and retailer write-ups (popularwoodworking.com, Lowe's customer notes) praise its smooth, low-vibration operation, excellent dust filtration, and well-balanced palm grip, and its Amazon average sits at 4.7. But high-trust community sources push back hard on power: one r/woodworking thread is bluntly titled 'the Bosch ROS is awful, don't buy it,' reporting it barely turns with an 80-grit pad under pressure, and r/BoschProPowerTools users call the GEX 'utterly underpowered.' We surface that disagreement rather than smooth it over.
What reviewers liked
- Expert and retailer reviewers praise smooth, low-vibration operation and dust filtration
- Well-balanced palm-grip ergonomics noted across reviews
- Strong 4.7 Amazon average across more than 600 reviews
Where it falls short
- High-trust r/woodworking thread calls it 'awful' and underpowered with coarse grits
- r/BoschProPowerTools users describe the GEX as 'utterly underpowered' for heavier work
- Sold bare-tool only; better suited to light finish sanding than aggressive removal per critics
