Black & Decker 20V MAX* 12" String Trimmer/Edger Review

4.2 out of 5

The Black & Decker 20V MAX* 12" String Trimmer/Edger, model LST320C, has proven to be a reliable companion for my lawn care needs. From its lightweight design to its efficient cutting capabilities, this tool brings a balance of convenience and performance that makes it suitable for both casual and more dedicated users.

One of the standout features of this trimmer/edger is its high-torque transmission. This allows the tool to cut through overgrown areas with relative ease. Whether I’m dealing with thick grass or the occasional stubborn weed, the LST320C handles the task admirably. The 12-inch cutting width is sufficient for most home gardens and lawns, allowing for swift progress without compromising on precision.

Equally impressive is the automatic feed spool system. This feature eliminates the need to bump the trimmer against the ground to advance the line. The trimmer line is fed automatically as needed, which keeps the workflow smooth and uninterrupted. This is particularly convenient when working on larger areas, as it minimizes downtime and frustration.

The lightweight design of the LST320C cannot be overstated. It’s easy to maneuver, and the adjustable handle and height settings make it comfortable for extended use. I found that even after prolonged periods of trimming and edging, fatigue was minimal. This is a crucial aspect, particularly for those who may not have significant upper body strength or who prefer a tool that is easy to handle.

The ability to convert from trimmer to edger is another practical feature. The transition is quick and straightforward, allowing me to switch between tasks without hassle. The edger function works well for creating clean, defined borders along flower beds and pathways, giving the lawn a well-maintained appearance.

In terms of power, the 20V battery delivers a reasonable amount of runtime. For smaller to medium-sized yards, one battery charge is generally sufficient. However, for more extensive areas or heavier trimming tasks, it’s advisable to have a spare battery on hand. Charging the battery can take some time, so planning ahead and ensuring that batteries are fully charged before starting is recommended.

While the performance of the LST320C is commendable, there are a few aspects that could be improved. For instance, the battery life, though adequate for most tasks, could be extended. During more intensive sessions, the battery does tend to drain faster, which can be a bit inconvenient. Additionally, the power output, while adequate for grass and light weeds, struggles slightly with thicker, more robust vegetation. It’s essential to manage expectations and understand that this tool is best suited for regular lawn maintenance rather than heavy-duty clearing.

Another point of consideration is the safety button. While it’s a necessary feature, it can be somewhat uncomfortable to hold down for extended periods. This minor inconvenience may require occasional breaks to relieve hand strain, especially during longer usage sessions.

Durability is another aspect where the LST320C shows mixed results. While the main unit feels sturdy and well-constructed, the trimmer line spool cover and other smaller components could benefit from more robust materials. Over time, these parts may require replacement, which is something to keep in mind for long-term ownership.

Despite these minor drawbacks, the Black & Decker 20V MAX* 12" String Trimmer/Edger offers excellent value. Its ease of use, efficient cutting, and versatile design make it a worthy addition to any homeowner’s tool collection. The convenience of a battery-powered unit, free from the constraints of cords or the mess of gasoline, further enhances its appeal.

For those looking for a reliable and user-friendly trimmer/edger, the LST320C is a solid choice. It excels in providing a balance of power and practicality, making lawn maintenance a more enjoyable and less daunting task. While it may not be the best fit for extremely large or heavily overgrown areas, it performs admirably for routine lawn care and edging needs.

In conclusion, I would recommend the Black & Decker 20V MAX* 12" String Trimmer/Edger to homeowners seeking a lightweight, easy-to-use tool that delivers consistent performance. Its strengths lie in its maneuverability, automatic line feed system, and the convenience of battery power. Though it has some areas for improvement, particularly in battery life and component durability, its overall performance and user-friendly design make it a worthwhile investment for maintaining a neat and tidy lawn.
