What Customers Are Saying

The Kobalt cordless string trimmer offers a powerful 80V brushless motor that can handle thick weeds and tall grass effectively, comparable to gas-powered models. It features a long-lasting 2.5Ah battery with quick recharging, providing over an hour of runtime. The lightweight and well-balanced design is easy to maneuver, though some users find it a bit heavy. The trimmer operates quietly and offers adjustable handle and two speed settings for good control and flexibility. However, some users struggled with restringing the trimmer head, and there are concerns about the availability of replacement parts and long-term durability.

Nice trimmer with two flaws

Would Recommend

Powerful trimmer clears out thick weeds. I does the job very well. Battery lasts long enough to clear out the 40 yard ditch on my property. Downside #1. I was able to buy replacement string heads for other trimmers I have owned. They just snapped in place, very easy. There are no replacement heads for this. I have to manually re-string the head which is time consuming and frustrating. Downside #2: The shield at the end of the pole is too small. I get pummeled with debri from head to to...

string doesn't work

Would Not Recommend

The string doesn't come out automatically like most weed eaters. you try to tap the bottom and nothing happens. trying to restring it is very difficult also, plus didn't help.

Strong cutting makes short work of yard work.

Would Recommend

As a long-term fan of Kobalt yard products, I have passed my enthusiasm on to my adult children. So when my oldest son asked for a string trimmer for his birthday, I ordered this one. He has been very pleased with the performance and ease of use. While the 80volt model is heavier than any other battery powered trimmer he used in the past, the weight is within limits and is balanced, and the power is great. Kobalt is my go-to yard equipment.

Great power of battery operated

Would Recommend

This trimmer has the power I had hoped for. Only used once at this point but pleased and would recommend. The reason I gave 4 stars is the delivery was not predictable. Did not arrive when originally told, took a couple of days to give an update, then did not arrive on the date given.

still waiting

Would Not Recommend

ordered this trimmer 2 weeks ago with an estimated (per website) delivery of 4 days from time of order. When I check tracking, a new 'delayed' note appears. Three 'delayed' notices later....no trimmer, no status, plenty of weeds

Expensive Junk

Would Not Recommend

The spool popped off, and an eyelet got lost. You can't buy just that part. The head doesnt come off easily, but if you get it off, you can't buy a replacement. I went to Lowe's, helped get the head off, but the replacement heads will NOT work.

Weed eater

This weed eater works very good. The only complaint is the battery life on setting 2… I have bought a 5amp battery to replace the 2.5 amp that comes with it.
