They gave me this keyboard for my birthday, less than half a year later, the fasteners of the keys broke, one of which was not even really used (a point in the department with a calculator). They replaced it with a rubber one from the kit, it also broke. You won't find new keys during the day with fire. Found only on foreign sites, but their cost is almost equal to the cost of a new keyboard (about 50 bucks per set). Alas, the first experience with mechanics was not very successful :(
