At first, I had to get used to it for about a month. After the K360, it was not familiar (I used it for 7 years). Without even thinking about the left shift, it turns out that people have problems with it)). And the same goes for Enter. I bought it as soon as the first batch arrived in stores. In use for a year. And I didn't notice any problems. The software is not buggy (windows 10, modern computer), although a couple of times it did not show that charging was needed, it turned out that it asked for ates. I don't understand people's animosity towards him at all. Installed - configured - forgot. The battery will sit down, the backlight will turn off, the light will flash red. No, everyone needs an icon on the screen to show what needs to be put on charge)). It can be used as a wired one (but there will be no wireless cable operation mode). Connected with a cable and forgot about charging, the backlight will not turn off until you want to. There are no sticky keys. I pressed 10 pieces at the same time there are no problems. If you find fault, then not all the contours of the keys are highlighted "space", "plus", "caps lock". And also the uniformity of the backlighting of the contours trembles at medium brightness and below. Although if you unscrew the backlight to the maximum it is not noticeable. Everyone writes that it is not worth the money. I don’t know for me the price for this product is adequate, but you always want it for free . In, space in dollars is the normal price)). That's for Craft the price is too high, that's for sure.
