Purchased in 2022. Almost unused. I haven't touched it for about two years, but it seems to be working fine. I opened it once after purchase and used it for typing a few times (almost like new). There may be some minor scratches or dirt due to amateur storage, so please refrain from purchasing if you are sensitive to such things. I have performed a simple cleaning (overall cleaning, dust removal, etc.). Operation confirmed. All keys input confirmed. RGB light illumination confirmed. Thank you.
