For programming, you need to understand the manual for each program. The result, however, is that it works correctly.

I had bought various products, all of them were terrible. Two of them suddenly stopped displaying on the screen after a few days, then they started working again, but they were unreliable and some didn't even provide power. I decided to try the Brennenstuhl, solely because it is a German product, and it is indeed the only one that worked properly without any issues from the beginning and even after 4 months. It is evident from the menu and the overall quality of construction that it is a great machine. I bought two more!

It works perfectly, but I didn't give it the fifth star because the instructions for its adjustment are incomplete and unclear.
