Ordered one. It broke after 1st use. Gave it the benefit of the doubt and got a replacement. That one also broke after first use. Spend your money elsewhere ### ⭐⭐⭐⭐⭐ Quality Comes in Small Packages: This Sander/Grinder/Polisher Get it Done! *by on Reviewed in the United States 6 January 2025* This inexpensive, very compact device does what you need it to do and it seems like it will hold up over time to keep on doing what you need it to do. I was impressed by the design and apparent quality of components. Time will tell if longevity is a part of the quality, but for now it appears to be so.Belt sander, grinder, polishing wheel are all included. A circular saw blade may be attached at optional cost.The "brick" style power cord includes an 8 position switch to select rotational speed of all three features; sander, grinder and buffer. The electrical components all seem to be good quality. ## Frequently Bought Together - NuoDunco 3-In-1 Mini Belt Sander - Electric Bench Grinder Sanding Machine, 7 Adjustable Speed Table Polisher Buffer Handcraft System for Metal Wood DIY Craft Jewelry Stained Glass (Plus Kit) - SCOTTCHEN Buffing Polishing Cutting Compounds 4 Oz.
