Hychika Random Orbital Sander
Score: 85/100Rankings

The HYCHIKA OS300W is a powerful corded random orbital sander featuring a 3.8A motor and six variable speeds, making it a 'hidden gem' for budget-conscious users. It offers excellent dust collection and includes sandpaper, though some users note arm fatigue during long sessions. It is best suited for DIY hobbyists and light professional users needing affordable power for wood, metal, or plastic.

The Galax PRO GHJ-151 is a budget-friendly 5-inch corded orbital sander featuring a 280W motor and variable speeds up to 13,000 OPM. It stands out for including a dust collection bag and 15 sanding discs, offering great value for DIYers. However, the lack of vibration data and potential bulkiness are trade-offs for its price point.
