I bought it in February 2023. I used it for tough, tall grass and small reeds with a 3mm cord. Lightweight and well-balanced material. It easily changes the cord without any effort. However, after a lot of use, it collects dirt inside and it is very difficult to rotate the head to wind the cord. Several times, the cord also got stuck and wouldn't come out. Eventually, after 6-8 months of use, the head broke from hitting rocky ground, which is supposed to be made of aluminum.
I bought an Oleo-Mac (for three times the price) and found my solution. No comparison in terms of quality and none of the above problems. You can cut acres non-stop and hit it as much as you want.
For the use I need it and the way I use the machine, I wouldn't buy it again.

I used it once so far for over an hour. Very good tool. The adapters that fit all your machines are very handy. And very important that you don't need to open it to load the trimmer line. It is also very durable and seems like it will last a long time with proper care, of course.

Very user-friendly head.
First, I have used it on a lightweight Kraft trimmer.
The passage of the trimmer line is easy as it has a hole (instead of a fixed stopper). The diameter of the hole also determines the maximum thickness of the trimmer line (personally, I used 3.3 mm and the trimmer worked perfectly with it).
The head fits easily onto the trimmer and is well-balanced with no strange vibrations. The trimmer line release mechanism works normally.
I use it for hobby purposes, but the area is quite large (~5 acres)

So far, everything is good. I bought it to replace the Efco load & go because after 1 year, it would throw out all the trimmer line when I hit it on the ground. It is indeed 99% identical. I use it for household tasks.

Top!!! It went bam bam, durability, easy installation, and aluminum with a flexible spring handle to cast fishing line

Excellent.
With all the accessories to fit in all models.
Good quality of plastic and overall construction.
Very high quality

Quality plastic that appears quite durable (I will know after a few days of use). Easy way of inserting and wrapping the fishing line, easy detachment during use. The 3mm fishing line that came with it wore out quickly, but that's not a big deal. I ended up using a 3.3mm fishing line that I had and it worked perfectly. It went in easily, wrapped smoothly, and came out smoothly and progressively during use. The only downside is that by using a 3.3mm line, you sacrifice a bit of the length it can hold (in order to wrap properly). Having tried several different brands, I think this is one of the best. Of course, time and use will tell.

I bought it for a th48 toolbox! I haven't used it enough yet, but so far it seems to work exceptionally well! Time will tell its quality

Well done, very good head, made of sturdy plastic, not like Husqvarna's which is made of cheap plastic. It's worth it and in the end, it's not always true that you get what you pay for. I have moved away from the notion that something has to be branded to be good. Here, you pay for quality and not just the brand!

I bought it for a DBC 520, much better than its own, it fits without gaps on the corner, solid construction, very easy to fill, for the 8 euros I bought it, it's worth 1000% and I regret not buying two. Only the adapters it has inside to fit all brands are worth more. Time will now tell for its durability.

Easy installation and use without stopping the lawnmower constantly. Just fill it up and keep cutting. I have purchased two heads
