Purchased in 2020 and used at home. It was plugged into a power outlet under a shelf, away from sunlight, so the exterior is still very clean, and I was using it until just now. There is no outer box or instruction manual, so please obtain the manual etc. from the following link: https://www.buffalo.jp/product/detail/wex-1166dhps_n.html Wireless and wired connections are possible.
