What Customers Are Saying
Customers praise the trimmer's power and ease of use, with many reporting it outperforms gas models and handles thick weeds efficiently. The lightweight design, quiet operation, and long battery life—often lasting a full yard on one charge—are frequently celebrated. However, significant durability concerns emerge: many report spool covers breaking within months, bump feed systems failing, and string reloading proving difficult. Most frustrating is the unavailability of replacement parts, with customers unable to obtain covers or chargers, leading several to abandon the brand entirely. Overall, while performance impresses initially, long-term reliability issues and lack of support disappoint many.

Wack it GOOD
Would RecommendBought on close out/ discontinued. Has all the features I will ever need. Might want to get a second battery and string just in case they are not compatible with newer trimmers. Bought Dec.2019.

Kobalt 40 v 13" trimmer
Would RecommendI bought this trimmer to get an extra battery for my other tools as it was cheaper to buy the trimmer with battery than a battery by itself. Anywho, the trimmer works pretty good, has a small cutting area but cuts grass well. Not as heavy as my gas trimmer and much quieter. Since all Lowes stores near me don't sell the batteries in their stores anymore I am concerned they will quit selling Kobalt products in the future so I may not buy any more. Maybe Lowes will explain why we can't get replac...

Excellent Purchase
Would RecommendI had used an electric and gas powered trimmers all my life and now that I have carpal tunnel in both wrists, I am unable to withstand the vibration and weight of them. I used this trimmer my daughter purchased and loved how light weight it is and there's no vibration. I'm able to trim the whole yard with one charge. Once I'm done, I place the battery on the charger which is fully charged in no time.

Borrowed Kobalt 40v Trimmer
I borrowed this trimmer from a friend of mine and boy was I impressed. I'm going to get one for myself. Powerful and smooth cutting and for the price it's awesome

workhorse trimmer
Would Recommendpros: Strong, capable trimmer. Good battery life. Contrary to some reviewers experience I have had no problems with batteries or chargers and that includes other battery powered Kobalt yard tools. Being able to use the same battery on all of them is a big plus. cons: A little on the heavy, unbalanced side. My wife prefers a smaller lighter but less capable competitor's trimmer because it so much easier to handle. I am about six ft tall and have to hunch over to cut grass, no matter how the handl...

Replacement Head parts
Would Not RecommendThis trimmer was excellent for the first year of use. Once the bump head broke and the inner spring was lost, there are no replacements for the trimmer head. Bought a new bump piece, however no spring included and to this date I have not found an universal product that fits given the fact that an original head replacement is impossible to find. Im worry now as I bought a mower, blower, and hedge trimmer and if something else fails parts seem very hard to find.

Not GREAT !
Would Not RecommendBought this in May of 2019 and it stopped working today, 10/22/2019 this has been a major pain since day one. I have a 1/4 of an acre and it didnt make it 1 season. The trimmer design is comfortable but the feed system was none exsistant. You can bump the head and it will stick, then have to flip it upside down and pull the line out. I used the right size line and use 3 different brands and it was the same every time.

Typical Weed Eater...
Would Not RecommendIf you want something that hardly works after 6 months, this is for you! The battery last for about 1/3 of my tiny yard on the 2 power setting. After you go through what cord came on the weed eater, good luck threading it yourself.... it's not hard to spin the cord in a circle but getting it onto the weed eater without it coming undone every time is basically impossible.. it also does not feed itself after 6 months of use... so every time the cord grounds down, you have to stop and struggle to g...

First Cordless Edger
Would RecommendThis edger/weed eater is the best one, gas or battery, we've ever had. Easy to handle, and has string that lasts longer than the normal plastic one. Long lasting battery that is interchangeable with other Kobalt products.
