Not quite a five-star, but way better than a four.
This trimmer is totally killer. I love it. That being said, there is just one wee bit of a problem. The housing for the gear that spins the head gets super hot. When using twisted line, the line has a tendency to separate and melt just enough to cause the line to stick together, causing it to not want to feed and eventually break off inside the head. Easy solution: don't use the twisted line. Use single-piece 0.095-inch line and everything should be cool. I'll give it a 4.9.

Better than expected
This trimmer has more power than I had anticipated. Did a half acre of subdivision property and only used half a charge from the 9ah battery.

I hope I will only have to buy it once
I use it to cut tall grass and weeds that I can't get to with my mower. I also use it to edge around my driveway. Lots of driveway!

Great product!
The Milwaukee M18 string trimmer is even better than I expected. Took some time getting used to how quiet it was, especially compared to a gas trimmer. It has more than enough power to get any job done. Most the time I am not even using half throttle. The 9 amp battery seems to last forever. Love the string trimmer! My neighbor is desperately wanting to buy now. I am hoping to purchase the M18 hedge trimmers next!

Proud like a father to show it off. The Rabbit , Turtle feature is my favorite feature, then the M18 battery life is all the work I want to do at one time. Then also the batteries recharge so quickly. It's light and break's down so easy to go in my yard trunk. My brother used and was speechless, and that's Amazing.

Easy to use and so convenient!
I am a 67 year old woman. I help with all of the yard work and this is so much easier for me to use than the larger, gas powered string trimmer we have. We still use that one for tall grass and weeds but this one is perfect for all the trimming around the house and landscaping.

I really like this trimmer
I trim about 30 minutes each week. I got tired of trying to start my gas trimmer so when this came up at $100 off at HD I pulled the trigger. It came with a 9.0 battery & it works perfectly for my needs. I have many Milwaukee tools & they are in one word reliable. Would recommend to anyone.

can these trimmers be used in the rain ?
Shane P on Mar 29, 2019
BEST ANSWER: Milwaukee does not recommend this model to be used in the rain.
Will other m18 batteries work?
A shopper on May 22, 2018
BEST ANSWER: Yes, any of the M18 battery line will work. I have a small grass area and I use the 2.0ah batteries and get 15 minutes or so of runtime.
Can a blade be attached to the trimmer head to cut brush?
Andrew L on Mar 10, 2018
BEST ANSWER: No. This trimmer wasn’t made with that in mind.
do I need to buy a string pack or just rewind more string?
A shopper on Jul 1, 2017
BEST ANSWER: It's best to buy the string pack. Spoiling the string on yourself can be a pain in the neck. It can be done if you have some patience. However, if you want to save yourself the hassle, just buy it already strung. Hope this helps.
Is the length of the shaft adjustable for shorter folks?
A shopper on May 3, 2018
BEST ANSWER: No. that is a fixed shaft unit it is not adjustable.
Do you ship to UK?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
