Disadvantages:1. Weight: Weighing in at 53.1 pounds, this sander is heavier than many of its competitors, which could make transport, moving between workbenches, or storage challenging for some users.
2. Price: As a professional-grade tool, the cost of the 3M 77720 expanding drum sander might be a consideration for hobbyists or budget-conscious users.
3. Requires two hands: Due to its weight, this sander needs to be held and operated with both hands, making it a more involved sanding process than smaller, one-handed sanders.
Conclusion:The 3M 77720 expanding drum sander provides users with exceptional sanding capabilities, versatility for a wide range of projects, and a large sanding area, making it highly recommended for professionals and enthusiasts who require high-performance sanding solutions.
