2. **Battery Compatibility Issues** While it may work with some 20V batteries, compatibility isn t guaranteed across all brands. Users may need to purchase Senix-specific batteries, which could add to long-term costs.

3. **Build Quality Concerns** Some users report issues with plastic components wearing out faster than metal alternatives, potentially leading to premature failure under heavy use.
