Camden/Awid RFID Mullion Proximity Reader - 2 Part Systemstar rating 3Noelle BanuelosSeptember 10, 2009I like this but this is the second one we had had that went bad. We called the manufacturer but they would'nt even talk to us. Nokey replaced both quickly. When it worked it did work well. My advice is if you have to have this reader brcause it has some really good features just make sure you buy from a place that will stand behind it.
