"They contacted me."

You program it for temperature you want your tank to be. We received the chiller promptly and put it into use. I hope these suction cups work very well. I used to try those other cheap heaters sold on amazon. Seems to keep the temp n the tank fairly regular. The red light means it's off, blue light means the temperature is constant. The cover over the heating tubes is great, the turtles claws can't damage the tube.

Once attached to the tank wall I've had no issues with it coming off. We received the chiller promptly and put it into use.
