Your cart is empty.More durable. More flexible. Less hassle. Aero-Flex Line Blades are aerodynamically designed and engineered to perform best at low speeds. Flexible yet durable, our blades last longer than traditional plastic string and can be easily replaced without the hassle of spools, springs, or rewinding, and do not break on contact with obstacles. Plus, with four powerful blades attached at any given time, Aero-Flex Line Blades cut vegetation more frequently during each revolution for a more uniform landscape. With a more rigid design and greater mass than traditional plastic string, Aero-Flex Line Blades are capable of mulching, trenching, and mowing in addition to edging. Their neon coloring gives users additional visibility for their cutting radius so they can ensure they are only cutting what they want, where they want. Package is a mix of orange and yellow blades. Use two orange and two yellow for both clockwise or counterclockwise rotating trimmers.

I haven't had any issues. I use them at a slow speed as recommend and they have worked great for me so far. No complaints, the change out is easy and fast and they last. I recommend this product and I will buy them again

I had bought the same product at local merchants and was supposedly the same but didn't last close as long as this product. I got twice the merchandise for half the price so well worth it!

I bought this to replace the "bump" feeder line head on my Troy Bilt gas trimmer. I was tired of fighting with my old trimmer every time I ran out of line. I love how easy it is to pop the Aero-Flex blades in and go. I think they do a superior job cutting grass than my old line even running my trimmer at half speed. The design of the blades creates a lift that makes cutting grass easier. The key to these as I mentioned earlier is running the trimmer at a lower speed. I have almost an acre which includes a large stone wall and 2 fences, one a chain link/aluminum fence that encloses my backyard and the other a mesh/kid proof in-ground pool safety fence that I have to trim around each time I mow the lawn. I find that one set can last at least 4 trimming cycles before needing to be replaced. Going by this a pack of 32 can last me 4 seasons which, for me, makes it well worth the money. The only downside is that it wears very quickly when edging or cutting brush. I usually save these applications for when the blades are close to replacing. Lastly, I've tried the suggestion of using zip ties and found that they do not work. They do not cut grass well since they're orientated vertically when loaded in the head & I've found they break almost immediately upon hitting any obstacle.

I wish I had known about these years ago. I don't have to dread weed eating and messing with broken lines. I pop these on and it makes the work so much easier.

Kinda break easy. But if I go little slower with the whacker and not on high rpms they is good to go.

I converted my Troy-bilt (29cc, 4 stroke. straight shaft) trimmer head to the Aeroflex blade adaptor about a year ago. The improvement over the double-line bump head trimmer was amazing. For one thing, and I don't know if I have seen anyone mention this before, the aerodynamic qualities of the AeroFlex let the head spin much faster, to the extent that there is a subtle but definite lift. I have a very rough patch to beat to submission with all kinds of vines and woody plants. My impression is that the blades last past the point where, with the bump head, I would have had to bump about ten times--and hope that the line feeds correctly. That is the real problem with the bump head, of course. I would have stayed with the line instead of the aeroflex if the line didn't get stuck inside the head, over-feed, be difficult to rewind, etc. I am not talking just about the Troy-bilt I have now, but also about the last four trimmers I've owned in the last 25 years.I read the review of the gentleman whose blades broke quickly, and I am surprised. I have had none break, just wear down.The Aeroflex is a slight bother to reload, of course, but it is foolproof and quick enough.Here's a tip: By the big bag (32 or so) from Amazon. Cheaper, and you are set for the summer. My big box store seems to run out the smaller packages frequently.Update 30 Nov 2015: In the time since the first posting, I have had some break off, if I am chopping though tough vegetation, or hitting some rocks. And for sure, they do wear down, in direct proportion to what I am cutting. I still get equal or better wear from them than my previous self-feeding systems.

These fit perfectly with products that require Aero-flex brand trimmers. This will work great if you have short and thin grass, but if you have tall weeds or hay, it does not last long.
