Used for just over one year! Kept in very good/clean condition (no shedding animals and I'm crazy about washing my hands). Selling because I am redecorating my office and I'd like to have all the matching pink Razer peripherals. Sorry to my husband who thinks I'm crazy š Works perfectly, no flaws at all! A really great keyboard. https://www.amazon.ca/Logitech-Spectrum-Mechanical-Keyboard-920-007739/dp/B01BBKYM3I
