Very powerful for its size.
Very user-friendly due to its small size.
Excellent choice for amateur (and not only) applications.
A great advantage is the battery interchangeability with other devices
(if you have any) from the same company - this way you save on buying
a charger and battery.
Based on the amateur use that I do, I haven't found anything negative in its operation so far.

I have only positive comments to make:
1) No more wasting time with painful screwing and unscrewing of the head to change the trimmer line.
2) No more interruptions to change the trimmer line.
3) Changing the trimmer line now takes only half a minute without screwing and unscrewing the head. However, you need to have pre-cut trimmer line pieces with a maximum length of 40 centimeters.
4) The sample trimmer line that comes with the head is very durable. The ground I trim every year is rocky, causing trimmer lines to wear out quickly, even when using thicker ones. However, this specific one lasted without needing a replacement.
5) I have automatic plastic heads and other aluminum heads in my arsenal that require screwing and unscrewing to change the trimmer line. Well, I have eliminated all of them and now only use this head.

Without exaggeration, I consider this head to be unique, and I genuinely applaud the person who designed it.

Having read various comments about this particular model as well as its cheaper counterparts in the same series, I had already clarified in my mind what "issues" I would encounter.

Specifically, the power supply and the volume.
For the power supply, I used a Samsung one that I had left over from a mobile phone without any problems, and for the volume, I used the dual-use on/off - volume switch located on the converter. (This way, the adjustment of the sound volume is done manually only from the converter, after you have first selected the audio output through the optical digital audio cable from the TV's settings menu.)

The TV that I connected the converter to is the LG 28TL510S-PZ and the headphones are Sony WH-1000XM4.

Conclusion: in my case, it does what it promises at a very reasonable price.

Very good, lightweight and user-friendly!!
