You want to get a wired one. This means the wires are already set up in the controller and all you have to do is plug the controller cord into a wall outlet and the heater cord into the controller. The non-wired ones would require you to have basic electrical knowledge because you'd have to hook up the wires inside the controller yourself.
Be warned that they're still capable of going bad. People were talking about how great and constant titanium heaters with controllers were, so I spent a bunch of money and got them. Then something went out, either my controller or my thermostat probe, and I came home in the winter to a tank at 67 degrees. I had some VERY unhappy cichlids. Of course, the way my luck runs it was probably a fluke and would never happen to anyone else.
