Pros
Pro Perfect for small jobs
This trimmer has enough power to do pretty much every small domestic job you might come across. Additionally, this trimmer has a short yet precise string perfectly suited for small-sized jobs.
Pro Extremely light
This string trimmer is, in fact, one of the lightest trimmers available on the market. It weighs only 5.2 pounds, meaning that it's easy to carry around by pretty much anyone.
Pro Can be used as an edger
If you rotate this unit's shaft, you can convert this trimmer into an edger, so you can finish your garden work by straightening the grass at the sidewalk. While the edging function works well, it does take some time to become used to it, as no wheel supports the trimmer while you are doing the job.
Pro Very good for stubborn weeds
The 2-stroke engine is powerful enough to cut thick grass and though weeds, while still maintaining a low weight.
Pro Anti-vibration system minimizes the tiring effect
The anti-vibration system of this trimmer reduces the tiring effect to your hands that's caused by vibrations, when you use the trimmer for an extended period.
Pro Good multi-functionality
You can buy optional attachments like an edger, hedge trimmer, pole saw, or a cultivator tool, to increase the functionality of the trimmer.
Pro Easy to carry around
Weighing only 10 pounds, this trimmer can easily be carried around the yard.
Pro Excellent warranty options
Hitachi offers a seven-year limited warranty, so if it gets defective within that time, you can take it to a service center near you to have it repaired for free (as long as user error didn't cause the damage). Also, the shaft has a lifetime warranty against rust.
Pro Can reach difficult areas
The 60" long shaft further means this is versatile enough to reach difficult areas.
Cons
Con May need an extension cord
Keep in mind that this unit is a corded, so you may need to provide a long enough extension cord to cover places you need to trim.
Con Unusual string release mechanism may be difficult to get used to
While most of the trimmers release the string either based on the resistance or releasing it when you bump the head against the ground, GreenWorks have decided to do it differently. The trimmer releases the string when you release the power trigger. For some, it may be hard to get used to this system.
Con Not meant for tall people
If you are taller than 6', it can be tiresome for you to use this trimmer for long periods of time, due to its size.
Con Maintenance isn't particularly simple
Since this trimmer has a two-stroke engine, you have to mix gas and oil before filling up the trimer. Not everyone likes this process, because spills and the smell of gasoline are almost unavoidable. On top of that, it requires maintenance like regularly changing or cleaning the spark plug and the air filter.
Con Sneaky line feeding mechanism
The automatic line feeding mechanism doesn’t work well with all the string types.
Con Can get pretty loud
The trimmer can get louder than 100dB, so it is recommended to wear hearing protection and not work with it during rest hours.
