I mainly use them for heating in my aquariums. A bit pricey for this type of use but aquarium pet heaters are the worst, they are not accurate, stick 'on' etc. With Ranco I hook my heaters up to this and let them control the heater. It does its job well and doesn't drift or grab constantly. So, in the end, the security and accuracy is worth a small part of the extra cost.
