Next on our list: EGO Power ST1521S. Our team is amazed by the carbon fiber shaft of this unit. It is indeed incredible to use this product as they have found a way to bring landscape tool users into the world of durable carbon fiber. 

This string trimmer is lightweight and robust. It is impossible to break the shaft with carbon fiber as it weighs far less than steel.

However, we are not convinced by the weight distribution; it is a bit uncomfortable balancing the equipment.

  • This unit comes with a spiral twist of 0.095In. Line

Moreover, it starts with a couple of pulls. The throttle response is outstanding, and we are amazed by the 2:1 gear reduction that eventually multiplies the torque output.

The explosive cutting power is comfortable and does not require much power from the handler.

Things to consider while buying a string trimmer:

A string trimmer fills all the gaps in a lawn mower’s performance. Be it; leftover weeds, unsightly flowers, or the untrimmed edges of the fences. However, it would be best to consider some significant factors before purchasing. 

Pay Attention to the Power source:

There are different types of models: gas-powered, electric, and battery-powered. The gas models offer outstanding performance, perfect for more extensive lawns and commercial purposes.

On the other hand, electric motors are portable and more affordable. However, they do not entertain heavy-duty use. 

Cutting Width is important

The dimensions of the cutting diameter are equally important. You need to understand the purpose of buying a string trimmer.

The cutting edge varies from 10-18 inches, and it also depends upon commercial and non-commercial usage. 


The shaft style also matters a lot. A straight shaft is ideal for tight trimmings and narrow spaces.

A curved shaft is suited for hard-to-reach spots and offers greater control. The adjustable shaft is a combination of both curved and straight.


Dual lines are cut twice, perfect for heavy-duty tasks on large lawns. On the other hand, single-line heads are easier to operate, ideal for small yards and gardens.  

How we Tested String Trimmers?

Since I shifted to my new place, I wanted to get a string trimmer. After all, I invested a lot of time and effort in designing the garden according to my wishes. I didn’t want to end up with a trimmer that would fail me in any way.

So I set out to conduct some serious research on various models available in the market before making a purchase decision.

However, I knew it wouldn’t be easy to compare all the trimmers available.

Moreover, after hearing about the experiences of my friends, I decided to test them on my own. If you are also in a similar situation, it is important to know the details of the trimmer you plan to buy. Keep on reading.

Power Type:

It is important to understand the power type of your trimmer. It can either be a gas-powered or electric-powered one.

While the electric-powered ones are easy to maintain and require less maintenance, they are quite limited in range and power than their gas counterparts.

On the other hand, gas-powered trimmers provide more power and range than their electric counterparts. Moreover, they can also be used for cutting thick grass and weeds.

Power Output:

After the power type, it is important to understand the power output of the trimmer. Generally, electric-powered trimmers have lower power output than their gas counterparts. However, you can find various models with different power outputs, so it is important to compare them before making a purchase decision.

Moreover, it is important to understand that the power output of the trimmer also influences its noise level and weight. A friend of mine bought a trimmer with greater power output; however, it was quite heavy for him to handle.


The trimmer’s weight also plays an important role in determining its usability and user experience.

Generally, lighter trimmers offer better maneuverability as compared to their heavier counterparts.

Furthermore, they are easier to manage and store. I wanted the string trimmer to be manageable, as I can only hold it for a short time if it turns out too heavy. So, I ended up choosing a lightweight trimmer with great power output.

Noise Level:

The noise level of the trimmer is an important factor before you decide to buy one. Generally, electric-powered trimmers are much quieter than gas ones. However, the noise level of the trimmer also depends on its power output.

Therefore, it is important to remember that a trimmer with greater power output will also generate more noise. I prefer buying string trimmers with lower noise levels as it helps me work without disturbing others around me.

Not to mention, my dog is also quite sensitive to loud noise.

Cutting Capacity:

Cutting capacity of your trimmer was an element that my mother strictly mentioned, as she struggled with her previous string trimmer on this part. It should be powerful enough to cut through thick grass without any difficulty.

This can be judged by looking at its blade size and power output. If you are looking for a trimmer that can handle thicker grass, you should opt for a larger blade size and greater power output. It is also important to ensure that the trimmer has an adjustable speed option, as it will help adjust the speed according to your requirement.

Furthermore, some trimmers have additional features like edging, which can help trim edges and corners. Therefore, it is important to consider the cutting capacity of your trimmer before making the purchase.


Last but not least, I considered the maintenance requirements as well. Generally, electric-powered string trimmers have fewer maintenance needs than their gas counterparts.

It is important to ask about the maintenance needs of your trimmer before making a purchase decision. Moreover, it is also important to read the instructions manual carefully and follow them properly to keep your trimmer in good condition.

Trimmer’s head:

The trimmer head is an important feature that needs to be considered while purchasing a trimmer. Generally, the trimmer heads are made from plastic or metal and come in various sizes.

Plastic heads offer better maneuverability; however, they can get damaged easily if used on tough terrains. On the other hand, metal heads are more durable and can be used on tough terrains.

I chose a trimmer with a plastic head as I knew my garden wouldn’t have too much rough terrain.

Cord length:

The cord length of the trimmer is an important factor to consider while making a purchase decision. Generally, it comes in two forms-long and short cords.

Longer cords offer greater flexibility, while shorter ones are better for smaller gardens. I chose a trimmer with a longer cord as I have a large garden and wanted to use it without moving around too much.


String trimmers are an essential tool for any homeowner’s lawn care needs. They are great for trimming grass, weeds, and other lawn debris to keep your yard looking neat and tidy. But before you purchase a string trimmer, there are some important questions to ask yourself.

What type of trimmer is best for my lawn?

The type of trimmer you choose will depend on the size and shape of your yard and the type of vegetation that needs to be trimmed. For smaller yards, electric string trimmers are usually the best choice because they are lightweight and easy to maneuver.

They also don’t require you to use gas or oil, so there’s less hassle with maintenance and refueling. For larger properties with more dense vegetation, gasoline-powered string trimmers offer greater power and longer run-time.

What safety features should I look for in a trimmer?

All string trimmers come with an adjustable guard or shield to protect users from flying debris, but it’s important to ensure that the guard is of sufficient strength and size before use.

Additionally, some models come equipped with specially designed handles and grip systems for maximum comfort and control.

How much power do I need?

A lower-powered electric trimmer should suffice if you’re trimming smaller grasses and weeds. For a thicker brush and denser growth, a more powerful gasoline-powered trimmer would be the better choice.

Also, consider factors like the width of your cutting swath and the weight of the trimmer when choosing a model.


Are you looking for the best string trimmer? There is not one, but many successful and suitable models available in the market.

Consider the factors that make a trimmer most suitable for you and then select the one that you like most from our list of tried, and tested string trimmers.
