very good head, the fishing line does not break easily, only the plastic cap should have had a different type of fastening because it got lost, otherwise I would have given 5 stars

I have worked with the Bosch electric one that I have, and it does its job just fine. The only negative is that it often loosens a bit, resulting in the strings coming out

Quite a good head. It would deserve five stars if it were easier and quicker to remove the strings from inside if they have been cut and if it had clearer instructions for beginners like me

Theoretically, it is perfect because it doesn't require tools, but practically, it is not. If you don't tighten it very well, the pieces of string will come off. However, if you tighten it too much, you might need a crowbar to open it, as I experienced a little while ago in the field.

First time using this type of head and I was very satisfied, it doesn't take a 4mm square that I tried to put, but even with the 3mm it's fine. If it breaks, I will buy it again.

Difficult to use and naturally expensive. They wear out very quickly and the cost of replacement is almost with every haircut (1 hour). Bad purchase

What they don't say is that when the manufacturer specifies two screws, we shouldn't put in all four, even if we have them. I put in all four screws in a new Kraft machine, and I almost burned it. As soon as I removed the two, it worked perfectly.

And what they don't include is a proper screw to attach the head to the machine, because the machine's screw may be larger and not allow for proper tightening. This happened with the aforementioned machine.

However, as a head, it is great, simple, and easy.

Excellent!
Very easy replacement of the trimmer line, just needs to be inserted correctly: It should be inserted in a way that it just comes out from the other side, without protruding.
It is very easy to install on the lawnmower.

It is not practical because it goes in and out from the same side. So you have to put 2 locks in total

Put double cement in one hole of the head and nothing in the other hole and cut strands. Also, the metal rod goes in first and then the cements go in.

It is really easy to install and use, but it unscrews very easily and the threads come off. The hole it has for tightening with my wrench opened up and I have to use pliers to tighten it. I bought a similar Italian one with a plastic cap and it holds better.

Quality accessory, a little difficult to open and close but we will get used to it. In the first test, I lost a screw, but it was probably my fault. After that, it worked normally, in combination with an aluminum screw, I also bought another screw head. Below is the review and test, I will come back if anything changes - https://www.youtube.com/watch?v=9f8TdEuM3jM

The best. From the moment I put it on, I found my peace! I left aside a bunch of other mosquito repellent systems! Simple to use and effective!

That the most honest and best value for money I really put it on my machine and found my health I highly recommend it for purchase !!!!!!

The only problem is that it does not withstand over time as the turns easily wear out, the whole system is threaded.

Very good. Solid lock. It fit in a Stihl and I found my health. Even the factory chain that it has inside is excellent.

Unbelievable head. Goes in and out fearlessly. I had an aluminum one and it broke when I took it out. This one is wonderful.
Also, the ease of putting on new fishing line is unmatched! Unbelievable!!!!!

For me, it is perfect. Because I have tried more expensive ones and I can say that they always had problems, for example, the fishing line would often come off, the screw would loosen, etc. This one, for 5 euros, is the best. I highly recommend it.

Very good for its price, no need for a key to tighten, tightens with the hand. Fits all machines that take a cutting disc.

Although it seems simple to use....sometimes it can be frustrating...sometimes it drives you crazy...sometimes you need (a screwdriver with a large opening) to unscrew it and put the thread back in....Other than that, for 5 euros, we can't ask for much....

Excellent head, I have been using it for years. Convenient and comfortable change of line. Durable over time. Very good price. Choose it and you will be satisfied.

Although I had concerns about its quality due to its price, this head pleasantly surprised me. It does exactly what it was made for, excellently. Easy and simple to install and use. The strings are easy to change quickly. A great product!

It is similar to the Oregon Jet-fit.
Only that logically it is a different construction... It worked fine

Simple and durable accessory, easy change of line, 1.5 cm low grass approximately without changing the line, the only thing that needs attention is the adapter wheel for proper alignment on the axis, if the existing one does not fit, you can easily find or make another wheel
