As soon as Claudia arrived, I had the impression that she was either wanting the service or had already used it before I did, which made me feel a little bit embarrassed about my buttons. (It goes without saying that I will not make any other purchases through POSITRONICS.) With its positives being: My first experience with a mechanical keyboard; previously, it had been mounted on a membrane. I really enjoyed how responsive the keyboard was, and the clicks were pleasant and not overly loud. In general, I think I could be satisfied with it. Some cons: On May 17, the keyboard was finally delivered to me, and on May 25, it became impossible for the keyboard to switch on. There was no reaction when the button was pressed, and the backlight did not burn. Before then, some keys were pressed five or six times instead of just one, but I figured this wouldn't be a problem in the end. I chose not to deal with it because there was a guarantee; I did it anyhow, and now I'm waiting for a return on my investment.
