However, at 229 pounds, the sander is quite heavy, making it less portable. Additionally, while it does have a speed of 1725 RPM, it lacks variable speed control, which might be a limitation for those needing different speeds for various tasks. The warranty is decent, offering a 5-year cover, though this drops to 2 years for commercial or industrial use.
