Compared to the WORX model, the Glenvera is often less expensive, making it a great value for those new to yard work. However, it may not have the same power or features as higher-end options. The battery life is decent but might not last as long as competitors.

While it is similar to the WORX and Glenvera models, the BLACK+DECKER offers a more sturdy motor and an Automatic Feed Spool. This system automatically feeds the line when needed, eliminating bumping and interruptions. However, the tradeoff is that it can be slightly heavier than others.

The HEYWORK 20V 12″ Cordless String Trimmer is known for its powerful 8000 RPM motor. This strength makes it suitable for tackling thick weeds and grass. Its ability to switch between trimming and edging enhances its versatility.

Compared with the other models, HEYWORK stands out for its high-speed motor, which can provide an edge in cutting performance. It may not be as lightweight as others, but the power compensates for it. Users should consider how this weight affects their comfort during use.

The Greenworks 40V 12 in String Trimmer is part of a combo with a blower. This model is designed for those who want a multi-functional tool for yard work. The 12-inch cutting width and its power make it capable of handling stubborn weeds.

In comparison to other trimmers, the Greenworks combo offers added benefit and versatility with its blower. However, you do pay for the added features, making it a less budget-friendly option. The trimmer itself is reliable but may not have the same power as standalone models.

One limitation is that the combo can be bulkier and heavier, which might not be ideal for everyone. If you are focused solely on trimming, this may not be the best fit. Yet, it is a good option for buyers wanting multiple tools in one package.

Pros

  • Combines a trimmer and blower in one package.

  • Powerful enough for thick weeds and grass.

Cons

Compared to other options, the CRAFTSMAN provides a good balance of power and runtime. Its lightweight design makes it easy to handle, and the adjustable height feature adds comfort during use. However, some models may have more advanced features.

One limitation is that while it has a strong runtime, it may not have the same cutting power as heavier-duty options. If you need a trimmer for really tough grass, you might find it lacking. Still, it’s a solid choice for average users.

When compared with other trimmers, the Makita excels in efficiency and reduced emissions. However, it may lack the cutting power of some heavier models. Users focused on power may find it less effective for tough jobs.

How We Reviewed

Where our data comes from

We gathered information from reputable online retailers, manufacturer specifications, and customer reviews. This data helped create a reliable picture of each string trimmer’s features and performance.

How we built this shortlist

We looked at over 30 different string trimmers based on features, price, and customer ratings. Only those under $100 and with solid performance ratings made it to this shortlist.

What we ruled out and why

Products that did not meet our price criteria or had poor customer reviews were removed. We avoided any trimmers with less than a 3-star rating.

What we did not do

We did not test any products by hand or take lab measurements. All data was collected from online sources without creating scores or testing results.

How often this page is updated

This page will be updated regularly as new models are released and older ones are discontinued. We aim to refresh the information every three months.

What to look for

Power and Performance

Power is a key factor when choosing a string trimmer. Look for models with higher RPM (revolutions per minute) ratings for better cutting ability. A higher RPM means the trimmer can cut grass and weeds more efficiently. Most trimmers range from 6,000 to 8,000 RPM. For heavy-duty tasks, consider those with at least 6,500 RPM.

Battery Life

Battery life is important for cordless trimmers. Aim for a model that lasts at least 30 minutes on a single charge. Many users find that a runtime of 60 minutes is ideal for larger lawns. Check the battery capacity, measured in Ah (amp hours), as this will affect how long the trimmer can run before needing a recharge.

Cutting Width

The cutting width impacts how fast you can trim your lawn. A wider cutting width will cover more ground quickly. Most string trimmers have cutting widths between 10 and 15 inches. For average yards, choose a trimmer with at least a 12-inch cutting width to balance efficiency and maneuverability.

Weight and Maneuverability

Consider the weight of the trimmer. A lighter model allows for easier handling and less fatigue. Most cordless trimmers weigh between 5 to 10 pounds. If you have a larger yard, a lighter trimmer can make a big difference in comfort and control during longer trimming sessions.

Versatility

Many trimmers now offer 2-in-1 functions, allowing you to switch between trimming and edging. This feature can save time and reduce the number of tools you need. Evaluate how easily a trimmer can convert from one function to another to find the best option for your lawn care needs.

How to Choose String Trimmers

Identify Your Lawn Size

Before buying, consider the size of your lawn. For small yards, a trimmer with a cutting width of 10-12 inches is sufficient. Larger lawns may require a model with at least a 12-15 inch cutting width to save time and effort during trimming.

Check Battery Specifications

Look for trimmers with lithium-ion batteries. These batteries charge faster and last longer than older models. Aim for a battery with at least 2.0 Ah for a good balance of weight and runtime.

Evaluate Weight for Comfort

Choose a lightweight trimmer to reduce fatigue. For longer use, look for models under 8 pounds. This will help you feel comfortable and in control while trimming.

Review Customer Ratings

Check customer reviews for insights on real-world performance. Look for feedback on battery life, ease of use, and overall satisfaction. Aim for models with at least a 4-star average rating from buyers.

Consider Additional Features

Some string trimmers come with features like adjustable height, auto feed lines, or 2-in-1 functions. Assess what features matter most for your lawn care tasks to find the right tool.
