    Great quality. Easy to switch out head. It was a little bit bigger than my current one, but fit perfectly and run great.

    This is a great replacement for the factory part included with some DeWalt string trimmers. It is far easier to load and is more durable.

    4.0 out of 5 stars Shouldn't have had to replace it in the first place, but here we are
    Reviewed in the United States on April 23, 2025
    Verified Purchase
    Highly disappointed with the head that came with my trimmer. With very limited use, it flew apart. A shame I had to already replace the head, but DeWalt says this is a better built part than the original, so we'll see. It appears to be a different type of plastic and installed easily ( reverse threaded, BTW.) It came pre-loaded with trimmer line. I'm just happy to be eating weeds again, time will tell if this one lasts longer than the original part. 4 stars for now. A $300+ trimmer head should have lasted longer than a few hours in the first place. Might change my rating after the season.
