I bought Claudia in the first days of official sales. The first button began to fail a year later (repeated pressing), changed under warranty in the city link. They issued a new keyboard, it turned out that this is the second (third?) revision. Materials have become cheaper, the black insert on the bottom left has been replaced with an unpleasant rough plastic (it used to be a pleasantly cold place for your thumbs, now it’s hot and disgusting there), the processing of the aluminum itself has become much rougher, the horizontal strobes in the material play unpleasantly in the light, drawing thick stripes right across the logo with a dragon. Some smart guy decided that the status LEDs (numpad, caps) were too bright, and significantly (!) reduced their power, while for some reason they changed the light guide so that now the light is visible only when viewed from the side (from the workplace, sitting at the computer). If you stand above the table, then the LED is not visible at all! It used to be very convenient when the backlighting of the buttons was turned off in the dark to understand where the keyboard is, and it looked like a lamp, like a matte terminator eye, but now these hidden diodes are just a waste of electricity. My bombing from these "innovations" is beyond words. The most annoying thing is that about two months have passed and the first key has already started to fail on the new keyboard (again repeated pressing). I regret that I took advantage of the warranty and exchanged my first keyboard. I had to be patient, order spare keys from China and solder it myself. In general, the keyboard is good. The shape of the buttons with bevelled corners is suitable for fast typing, a short stroke is also very useful. Compared to full-strokes, it almost does not ring on the MX. The set includes two types of ctrl and alt buttons, concave and convex, and this is not a decor, the difference between them is noticeable. The backlight is good, you can set it up conservatively and tastefully, the application is not needed. But the quality of new revisions (and, it seems, new keys) of Vigor is a complete bottom! I highly recommend looking for the first revision. It is not marked on the case in any way, look at the LEDs at a right angle and at the material of the black strip under the gap.
