## Product: Milwaukee M12 FUEL SURGE Hydraulic Driver
**Brand:** Milwaukee

## Pros

- Lightweight design helps reduce user fatigue during extended use
- Quiet operation allows for comfortable, prolonged work sessions
- Effectively turns rough tasks into precise, clean results

## Cons

- Lacks meaningful power for more demanding tasks
- Trigger control is unreliable or insufficient for precise operation
- The device does not meet expectations based on its claimed power
- The hydraulic fluid was leaking upon unpacking in some cases
- Weight capacity claims are misleading; only supports about 100 FT. LBS, not 450 FT. LBS
- Heavier than comparable models, which reduces portability
- Delivers less power than the MLW2553 model, impacting efficiency on tough jobs

- Some users feel the surge feature and power levels are underwhelming given the price

## Bottom Line

This Milwaukee 2551-20 M12 FUEL SURGE offers a compact and lightweight option perfect for tight spaces and lighter tasks, but it falls short on power and performance for demanding jobs. The surge feature is largely ineffective, and some build quality concerns like trigger durability may impact long-term use. If you're seeking a more powerful tool that can handle rigorous fastening or heavy-duty work, you might want to consider models like the Milwaukee M12 FUEL Impact Driver. However, for quick, precise, and less strenuous tasks in tight quarters, this could still be a handy addition to your toolkit.
