What Customers Are Saying

Customers praise this cordless trimmer's impressive cutting power and lightweight design, with many noting it handles thick weeds and edging tasks easily, often matching gas models on yards up to one-third acre. The brushless motor and bump-feed system earn consistent appreciation. However, battery life proves inconsistent—typically 15 to 25 minutes on high settings—prompting many to recommend purchasing a second battery. Durability concerns emerge around plastic components like the spool cap and guard, which some report crack easily. Despite these drawbacks, most customers remain satisfied with overall performance and convenience.

WHERE CAN I GET A SPOOL

Would Not Recommend

The Trimmer is awesome, but you can't find the replacement spool anywhere. You can't get in contact with Craftsman to ask them about it and on the product reviews where people ask about it or complain, they won't give an answer to where you can get a spool, instead they say they will reach out. STUPID.

Extremely satisfied

Would Recommend

[This review was collected as part of a promotion.] This is the first Non gas powered trimmer I’ve ever owned, much less cordless. I was extremely reluctant, but got it when it was on sale because the wife wanted one that she wouldn’t have to struggle trying to start. Within five minutes of using it I was completely sold. It does an absolutely amazing job, and can handle things that you would’ve expected to be too difficult for a cordless trimmer to make it through. The runtime per battery is ex...

String advane is horrible time-wasting and jams

Would Not Recommend

[This review was collected as part of a promotion.] As someone who has owned three different Craftsman trimmers in the past, this model is an absolute disaster that completely broke my brand loyalty. While the dual-string feature is a nice idea in theory, the string advance mechanism is atrociously designed and ruins the entire experience. The head constantly gets jam-packed with yard debris, and worse, it is completely unserviceable in the field—you literally have to stop working, track down yo...

Good weadeater for small yards

Would Recommend

[This review was collected as part of a promotion.] Good weedeater overall not made for large yards though. Ran through a 4ah battery and 2 bars on another 4ah battery in a 30 minute time period. Approximately 5 minutes run time on high and the rest was on low. Had issues with the bump feed at first and had take the head completely apart after receiving to fix it.

Outperforms my expectations

Would Recommend

I'm 52 years old and this weedeater is light enough for me to operate with one hand while standing on very steep ground. Absolutely LOVE it. Plenty of power on low speed for grass and most weeds. A single battery allows me to go around my entire 2 acres of fenced yard.

Material cracks easy

Would Not Recommend

Purchased 2 years ago as a combo set. I have replaced spools 4 times since cover cracks easily. Now the guard cracked and fell off and I am unable to find a guard to replace. Considering switching to different brand but all my tools are Craftsman 20v.

Do Not Purchase. Nothing but problems.

Would Not Recommend

Purchased at Lowes in the beginning of season, sometime in May. Worked great the first two times, After that the sting advance became sporadic. I had to advance it by hand. Then the spool cap became loose. I went to Lowes spoke with an associate who said there have been complaints but Craftsman came out with a new cap and spool to fix the problem. I purchased the new spool cap and spring ($6.99) and the new three pack of spool ( 24.99). I went home and the three pack of spool does not fit on th...

Right Power for Small Yard, Poor PlasticDurability

Would Not Recommend

If you buy this string trimmer, know that the head and spool cap are made of incredibly cheap plastic. After a year of use, the plastic started to really break down from normal use and just bumping the head for line feed. After two years I was trying to use products to glue the cap together. After three years the cap came completely apart. I had already purchased a replacement (which I had to purchase a whole new head because the spool cap itself for this model isn't sold anywhere I could find),...

Good replacement for my gas trimmer

Would Recommend

I like having high and low settings. I used the low setting when trimming around my hosta beds and it didn't dig into the ground like my old gas trimmer did. It was easier to control on low. And then I have a couple of hills where I used the high setting and it does great on high, even better than I expected. There are 3 things I don't like about it: 1.It's uncomfortable to hold. My right wrist was really uncomfortable after only 20 minutes. 2. It's great that it has an adjustable shaft but if y...
