I've never used a controller before, so be gentle. I bought a junior for the wife's tank. It came with 2 optical sensors and half a power supply (the little adapter bit is missing, the electronic bit is there). Isn't it supposed to come with 1 optical sensor and a full power supply? I have ordered a power supply from the amazon because I'm not going to mess about and they are cheap but I'll feel like a winner if they've give me an extra optical sensor in error (even if I've got nowhere to plug it in), lol. Can anyone confirm that I'm a winner?
