I've been using it for 4 or 5 years, I don't remember. If I'm too lazy to change the wire, then I'll buy the same one. : I repaired the wire with a soldering iron, I will use it for another 5 years. Its pros: Adjustable backlighting, embossed keys (in contrast to an absolutely flat a la Apple), quiet and elastic key travel. Everything is done extremely aesthetically and without pathos. Got cons: The wire at the base frayed, apparently, and became the reason for the shutdown. Left Alt and Shift are worn until there is no inscription, now there is just a light bulb) But at 4 years old. Oh yes, do not remove the keys, the fasteners are very fragile.
