You can erase the previously written words by spraying with water, and you can rewrite the user name and password at any time, which is convenient and simple. Acrylic material is strong and durable, waterproof, not afraid of damp environment, can be used in any environment and weather conditions. Got it for the office so Visiting guests can have access to the guest WiFi. A great purchase for house guests. Stuck with the internet username and password as defaulted.
