## Product: Milwaukee M12 Fuel Hackzall
**Brand:** Milwaukee

## Pros
- Compact size combined with strong power makes it highly versatile
- Easily handles cutting tasks like plywood, firewood, and small steel pipes
- Very powerful tool capable of demanding tasks, especially with larger batteries (4.0 or 6.0 Ah)
- Lightweight and one-handed operation for precise control and maneuverability
- Performs well as a reciprocating saw, with better ergonomics for extended use
- Milwaukee Fuel quality ensures reliable performance and durability
- Good for tight spaces and quick tasks due to its short stroke and design
- Versatile enough to replace some tasks typically done with larger sawzalls
- Made with high-quality materials, promising longevity
- Ideal for pruning small branches and general light to medium-duty projects
- Compatibility with Milwaukee's battery systems adds flexibility

## Cons
- Some reviews mention that the battery retention can be problematic, especially with larger batteries, requiring effort to remove batteries
- Widespread issues with battery systems from Milwaukee, including poor performance and difficulty in removal, affect user experience
- Arrives in non-factory packaging, which might concern some users about overall condition despite being new
- Slightly heavier than standard hacksaws when considering larger batteries
- Some users note that despite the power, the tool's battery release mechanism can be frustrating to operate, especially in tight spots
- The tool's capacity and performance depend heavily on using compatible and high-capacity batteries–smaller batteries may limit performance

## Bottom Line

This Milwaukee 2520-20 Fuel Hackzall offers a strong combination of power, versatility, and portability for a range of cutting tasks, especially in tight spaces. However, potential buyers should be mindful of battery system issues reported by some users, which could affect ease of use over time. If you're willing to upgrade to larger batteries and handle the battery release quirks, this tool is a solid choice for versatile, on-the-go cutting jobs. For an alternative with improved battery retention, you might want to consider other Milwaukee models or check out accessories that address this issue.
