What Customers Are Saying
Customers praise the trimmer's strong cutting performance, lightweight design, and impressive battery life, with most noting it handles thick weeds and edging tasks effectively. The 4Ah battery frequently completes full yard jobs on a single charge, even for larger properties. Users appreciate the ergonomic build, swivel head, and telescoping handle for reduced fatigue. However, a notable group reports persistent line feed mechanism issues requiring manual line pulling or replacement. Despite these frustrations, most customers still rate it positively, viewing feed problems as isolated defects rather than design flaws.

Would Recommend[This review was collected as part of a promotion.] Great trimmer for my small yard. Not a heavy duty trimmer by all means. Perfect for grass and lite weeds.

Good quality, goes through a lot of string.
Would Recommend[This review was collected as part of a promotion.] Have had this trimmer for a few seasons and does a great job. Only thing I would change is the automatic string advance, seems to waste a lot of string.

Great battery powered trimmer with dual speeds
Would Recommend[This review was collected as part of a promotion.] I am not sure why everyone seems to be negative and hating on this product. I have owned this Trimmer for at least 4 years now, since they first came out with this design and it works every time. Still have the very same trimmer today. It rarely fails to advance string when the button is depressed and in most cases that is due to the string being stuck to the line reel. I use all 4MP battery's and can usually cover my 1/2 acre lot with two batt...

Stops advancing the string
Would Not Recommend[This review was collected as part of a promotion.] I have owned 2 of these cordless string trimmer and when they work correctly I love them. The problem is that they quickly lose the ability to advance the string.i own many Craftsman cordless products and generally they are high quality tools. This trimmer doesn’t fit that category. The company sent me a replacement and it did the same thing.

Poor quality string
Would Not RecommendThis weed eater is light and has minimal vibrations compared to other weed eaters. However, the string is poor quality and breaks often, even when trimming grass. This weed eater really struggles and cannot handle anything thicker than grass.

Great product with too small of a guard
Would Recommend[This review was collected as part of a promotion.] This is a quality made and strong product. The only issue is the size of the guard. The guard is too small and doesn’t protect the user. Other than the size of the guard, it is an amazing product.

Auto and Manual Line Advance Stopped Working
Would Not Recommend[This review was collected as part of a promotion.] Has been a good trimmer, still trims well but a couple years ago the line feed (auto and manual) stopped working. I had just bought 5 or 6 new line spools so I have just been manually advancing the line by removing the cover and pulling the line out manually. It looks like the spindle that the spool fits on has worn down and the spool is binding on the spindle so it cannot rotate as it needs to to advance the line. Almost out of line so will ...

Faulty line feed
Would Not RecommendThe line feed doesn’t work. I have to manually pull out the line then I run it until the line breaks off and have to do it again. It feels like it takes double the time to get the job done.

Not a worthwhile product
I have the same problem as others. The line will not feed out. I have manually take the line cover off each time and hand feed the line out.

Stopped working
Would Not RecommendUsed it a few weeks ago and battery died.. recharged battery and there is absolutely nothing!! Stopped working all together. Been looking more into resolving the issue and not seems this is common. Only had a year! String feeder also never worked. Would have to take apart to get more string out. When it did work, it was great!

Works Great but comes apart!
Would Not RecommendWell it works great but like some other reviews, where the pole adjusts, it comes apart and won’t stay back together. I will vibrate so much it falls apart again so now it’s sorta useless.

Total waste of money
Would Not RecommendThe first use, it was great. Its never worked with any replacement spools. I have to manually pull line out to use until it breaks off. Then manually pull more line out. I have watched endless videos on how to properly load a new spool in, fix what may be wrong, and it has never worked.

Craftsman V20 4Ah string trimmer mdl # CMCST910M1
Would Not RecommendI have had this trimmer almost 2 years and really only used it this year after I had a new yard put in. I've had no issues until recently. I went into my shed to use it and the top and bottom pole had separated. I took out the screws at the adjustment clamp to place it back and it will not adjust. It will not go back together. I spent alot of money on it, and own all craftsman battery tools, and now it is useless. Broken without any fault of my own, walked in and found it hanging to the floor...

Self feeding feature will not work
I used it three or four times and the line ran out. Loaded new line and the self advancing feature will not work. I have to take it apart when I need new line. I am disappointed.

Weedeaters break in half with minimal use
Would Not RecommendI own 2 of these weedeaters. They worked great until they both began to break apart at the lever that adjusts the length. There is no way to tighten to keep the 2 pieces together. I have tried taping them. Nothing works. Now I have 2 weedeaters, broken in half, unable to be used.

Won’t Start
The weed eater is about a year old. Tried using it today and it won’t turn on. Battery is fully charged and properly inserted. This is pretty frustrating. I have worked around the feeding issues too. When working it’s a pretty good tool.
