I wish I could give -100 stars. Supposedly I bought a quality work tool that was replaced from the first day and the second one has the same problem. The battery indicator does not show and it charges whenever it wants. And the same goes for both. Guess what! I am not the only one, but in several reviews I searched for, the issue is known. It's a shame for the 100€

Undoubtedly expensive but undeniably good. The construction quality could be described as exceptional. The main reason I chose it was because it has a nozzle that creates a level spray (it doesn't spray to the right and left but straight ahead) like an equilateral triangle, with the liquid being sprayed at an angle of almost 90 degrees (fortunately, I found a presentation/review on the internet from someone who had tried the product and showed the different flows, otherwise I wouldn't have figured it out). In my case, this flow makes it ideal for annual spraying in the apartment building for insect control, as you can spray the desired surface with one pass without the problems caused by the conical spray, such as blind spots in the center of the flow and accumulation of droplets resulting from both the effort to cover the blind spots with repeated passes and the lack of stable pressure in the container, unrelated to the type of spray, which ultimately end up flowing on or dripping from the wall, making it simply a wet surface. The automatic pressure adjustment simply allows you to not worry about the issue and finish the job correctly, quickly, and effortlessly. The battery did not bother me at all. I charged it before starting the work, sprayed almost eight liters (almost two full fillings), and it is at 2/3 capacity. The pressure is also satisfactory. It could have been one or two atmospheres higher, but maybe it wouldn't have made any sense. Anyway, most are on the scale of 3 bar. So far, I have no complaints, and I hope it continues like this.
