I owned these for 3 years and it worked well. The auction is for a qty of 1 but I have 3 for sale. Please note 2 of 3 of the discs have a yellowing back and 1 of the 3 has a missing pull-out tab with the WiFi details but most people would create their own network name (SSID) and password so these would be unnecessary.
