Best String Trimmer Lines & Spools of 2025

"I have been using this line for over 20 years. It's durable and quiet when in use, and it works perfectly in anything that takes .095 trimmer line. It’s hard to find, but I was thrilled to get a package deal with my Weed Warrior trimmer head. I love how it performs and hope to find a 5lb roll someday!"

"As a long-time user of this trimmer line, I've found it works well in all my trimmers. It's tough and long-lasting, and when it's time to feed it, it does so easily. My only wish is for a higher visibility color so I can see it better in motion, especially around delicate areas."

"I was looking for a replacement trimmer line, and the difference with this product was like night and day. It's a bit thicker than what I had, but it handles Southern grass like a champ. I've already bought a second spool because I know I’ll want more!"

"I've been using this line for years without any issues!"

"I find this line has fewer sticking problems compared to other brands. The square design cuts well and breaks less often."

"I switched to this 2mm Dewalt line from a thicker brand, and it was very easy to thread. I'm definitely sticking with it."

"I find this Oregon 20-020 Magnum Gatorline to be a fantastic option. It lasts longer and cuts well, and I now only need to reload my trimmer every sixteenth time I garden. I can't recommend this line enough for my Echo electric trimmer!"

"After switching to this Supertwist line, I've noticed a slight improvement in cutting performance. However, I go through it almost twice as fast as my old line. For home use, it’s a decent tradeoff, but I wouldn't recommend it for commercial settings."

"Using this line with my Echo SRM 225 trimmer, I can easily get through 40 lawns a season with very few jams. It’s strong and reliable, making my landscaping tasks much smoother."

"I found the Oregon 21-380 Gatorline to be an excellent choice for both quality and value. It cuts through tough grass and weeds effortlessly, and the installation is straightforward, allowing me to get back to work quickly. For the price, the quality is unbeatable, and I would definitely recommend it to anyone needing reliable trimmer line!"

"I finally decided to try this line after needing to replace my Dewalt string. So far, it works well with my 18V trimmer and has impressed me with its strength. It's at least as strong as the Dewalt line, and I was worried it might break easily, but that hasn't been the case at all. I'm using it on everything from short lawns to stalky weeds along fences!"

"As a solo lawn care professional, I’ve tested a lot of trimmer lines, and this one is amazing. I've tried the Black Diamond Vortex, but this line is much more durable. It performs exceptionally well during maintenance runs, and its lighter weight means I can load more into the speed feed head. This not only saves me time but also makes my work more efficient, and the affordability is a huge bonus!"

"I've found these pre-wound spools to last significantly longer than the ones I used to wind myself. They make trimming so much smoother without interruptions!"

"Purchasing these spools of string was a breeze after I got my weed eater from Amazon. Such a hassle-free experience!"

"Changing this trimmer line spool is a cinch, and it holds up well while I maintain my lawn."

"I ordered string trimmer line .065 for my trimmer and received caps, springs, and 12 line reels. These parts fit perfectly and are a great value compared to local prices. I also bought a new trimmer that works wonderfully—it's lightweight and effective for slopes and scattered weeds. I'm impressed enough to buy a second set of wheels because my trimmer looks like a tiny lawn mower now. I absolutely love it! As someone older, pushing a heavy lawn mower is tough for my small yard, so this is a very efficient solution."

"I found this 16-pack string with four caps and springs to be a fantastic value. The auto-feed spool is a lifesaver, allowing me to extend the line without stopping. It's easy to use, light, and of great quality. I would definitely buy it again!"

"I’m thrilled with the supply of trimmer string for my Black and Decker trimmer. I trim a lot while mowing, and it can get pricey at big box stores—often $8 or more for a single roll. This box of 12 rolls, along with four trimmer caps, is a game changer! No more frequent trips to the store for expensive rolls. I might get another box just to ensure I don’t run out anytime soon. This purchase has been incredibly useful for me!"

"I was looking at other sets with only 14 feet and 3 sets, but this one offers way better value and is easy to cut with the included cutter. Since line tends to go quickly on trimmers, I appreciate having a good amount on hand. I'm very satisfied with my purchase!"

"As a user of the EGO trimmer, I find this line works well for me. While it may not be significantly stronger than the usual orange string, the 25% increase in strength really makes a difference!"

"This is my first time using the EGO trimmer line, and I can definitely say it feels superior to others I've tried. It cuts better, and even the sound it makes is not as harsh. I plan to buy it again once I run out, which will be a while since it comes with a good amount of line."

"I used to waste time rewinding my Black and Decker trimmer spool, but now changing it out with a new one is a breeze. No more tangles or knots! This pre-wound product is fast and easy to use. It’s made from top-quality materials, and buying in bulk has saved me a lot of money. Plus, it comes with replacement spool retainers and spool head springs, so everything fits perfectly. I highly recommend it!"

"I found this pack to be a great deal for replacement strings. It’s significantly cheaper than local box stores, and it works flawlessly. The two covers included are a bonus, especially since I often use my weedeater on concrete. They wear out slowly, but I can keep them new with these replacements. I just wish I had discovered them sooner!"

"After trying these spools, I’m convinced they may be the best value I’ve ever found. For the number of spools at such a low cost, they perform ten times better than the major brands. I feel confident they will last a long time. I’ve purchased this bundle a few times now, and it lasts me the entire summer!"

"These fit my Ryobi 13" trimmer perfectly. I was surprised that they arrived in a nice cardboard box instead of plastic packaging. The original line was terrible, but the line on these spools is actually really good. I might take a while to use them all up!"

"I used to make my own line, but I got tired of it. These pre-wound spools are reasonably priced, and I’m finding the twisted line works better and lasts longer. I had issues with my old line breaking too often, but I’m hopeful this one will solve that problem!"

"I always regret buying cheaper products. This is the first time I've used a whole spool without needing to refeed it constantly. The Ryobi line lasted longer and worked without problems. I'll never buy off-brand again!"

"These spools work great for my B&D trimmer. I love the pre-spooled design and the price is fantastic!"

"I found these replacement spools to be very effective. Installing the new one was hassle-free, just pop it in place!"

"These spools fit my Black & Decker Weedwhacker perfectly. The line lasts long enough for my entire lawn, and I got eight for a great price!"
