I was blown away
It's so quiet and powerful all at the same time. I couldn't believe how well it worked. I have about 1.75 acres and it will last long enough for me to go around everything I need it to. I have been recommending it to everyone looking for a new trimmer!

Just bought this tool, happy but battery life way to short took entire day to finish out back behind property, just long grass making a clear fire break! What normally would have been a two hour job w gas trimmer was all day and I had two batteries. Both died and couldn’t recharge fully, very long day!!!

Broke Spool and Line
I have not even trimmed my front yard of a small home plot and I have had to re-spool and thread at least 20 times and the spool broke. I initially used the stock line pre-installed but it was sheering off the spool head itself. Did not take long before I have to buy new line. Then I bought the round thicker line as per the manual and it still sheers off at the spool. Then to top it off the spool reel busted. The tool has power, and I love that fact, but when even at the low speed I can't keep the line from breaking.

Does the job
For most of your trimming needs you can use the low speed setting. The battery will outlast you on low speed. It has plenty of power on high speed to tackle stubborn weeds. The biggest don't have to rebuild your carb every year because of running ethanol fuel.

I usually wait to right a review, but I'm so happy with this trimmer, I couldn't wait. I just want to say thank you to the meth head that stole my Echo. This thing RIPS! No gas, no noise, no more tearing apart the carburetor, no more mixing gas and oil, no more waiting for it to warm up, no more smoke, light, powerful, super high RPM, head gets into tight places, I actually enjoy using it. I own the chainsaw which is why I got this and I love that too.

Great Lightweight product
Picked this up a couple weeks ago to replace a 4 cycle gas trimmer. This exceeds expectations. Lighter, just as powerful as gas. No hassle starting like gas trimmers. Only issue is the guard could be bigger to prevent clippings from covering you.

Better than expected
Plenty of power and battery life, plus swap battery if need more run time. Very easy to remove spool for refill. If used properly, you are hit with little if any debris. Use the right side to cut, that throws stuff forward. If you do not pay attention and start cutting left of center, stuff will start kicking back. This is true of any string trimmer, pay attention to how it works.

Decent, but not great
This trimmer has the potential to be amazing, but just falls short. First complaint is upon receiving it the spool was incorrectly wound. Not a big deal just not expected. I did notice until I first went to advance the line, one side shot out past the cutter and the other sucked back inside the head. Like I said, no big deal, couple of minutes to rewind the spool and I was off. That's when I realized the small guard on it didn't block much at all. I wear safety glasses when I trim for the occasional chunk that might get me, but with this trimmer it was constant. I read in the instructions there is a different shield you can buy, haven't found it any where though.

Now for the good, I used this for about 2 hours non-stop on the low setting and still had 1 light on the battery. Could have easily went another hour or so. On top of that, it is considerably lighter than the gas trimmer I usually use. I'm about 6 foot tall and the length was perfect for me, I'm guessing if you're much shorter though it may feel a little oversized.

Basically, if you're ok with wearing a face shield or getting hit with debris then this is a great product, otherwise hopefully they'll put a larger guard on the thing and then they'll really have a great product.
