Longer notes from the same comments we summarized above.

What people reported

Many owners find the Stihl FSA 57 to be lightweight and easy to use, making it a good option for different users, including those seeking a less strenuous tool. It offers good power for a battery-operated trimmer, effectively cutting through tall grass and heavy weeds. Users noted minimal clippings are thrown back towards the operator, which improves the trimming experience. Some owners are also pleased with the battery life and quick charging, allowing them to complete tasks efficiently.

Problems people mention

A significant number of owners report issues with the default trimmer head, specifically the 27-2 or AutoCut C 4-2 models. Users describe it as "underwhelming and frustrating," prone to jamming and being difficult to reload with string. Many resort to watching online videos or seeking aftermarket solutions, with some finding relief by removing a "white plastic part" that complicates the process. Another common complaint is the safety lever's placement, which some users find awkward or a "stretch to reach" with their thumb, requiring a specific hand position to engage the power switch. While some report good battery life, others find it limited, with about a half-hour of use before needing a recharge.

Where owners disagree

Owners have mixed opinions on the battery life. Some find that one battery charge lasts long enough to finish their yard work, even through "a fair bit of use," while others report a more limited runtime of around 30 minutes. There's also a clear divide regarding the ease of reloading the trimmer line; some, after finding a specific method or video, say it's "easy as pie," while others describe the process as consistently frustrating.

Who it's for

The Stihl FSA 57 is a good fit for homeowners looking for a lightweight, powerful battery-operated trimmer for general yard maintenance, including cutting through moderate to heavy weeds. It is particularly suitable for those who prioritize ease of handling over heavy-duty, gas-powered alternatives. Buyers should be prepared for potential frustration with the stock trimmer head's line reloading mechanism, and may benefit from seeking out online tutorials or considering an aftermarket head replacement.
