Power conditioners only have value for commercial applications. Nearly every appliance in your house likely has a power conditioner at its power intake, but none of that is actually going to save you money. The concept is based on energy companies measuring real vs actual power whereby the power factor (the ratio between them) is what is used to determine how much power you're using, therefore using power co diction era, you bring your power factor closer to unity and then save money on electricity.
Sounds great except that's only used in commercial applications and you get charged for massive machinery not having a power factor closer to unity.
In the home, power factor isn't considered at all, so your grandparents got 100% scammed. You can look up power factor and enmax to prove it to them if you like. My neighbour had the same thing in his head until I showed that stuff to him and he then decided not to buy the power conditioner.
