Should I overpay for a large aquarium heater with a lifetime warranty?

The recommended warranty period for any product, including large aquarium heater, depends on various factors, such as the use frequency, price, materials, and other details. Brands sell their most expensive products with a lifetime warranty, while the cheapest options come without any protection. We think that the optimal warranty period for a good large aquarium heater should not be longer than five years.
