Whether the lifetime warranty for a aquarium heater cover is useful?

Most manufacturer offer various warranty terms depending on the price of a aquarium heater cover. Some brands have expensive models with a lifetime warranty, while the others only offer one-year or two-year protection. The cheapest aquarium heater cover on the market may not have the warranty at all. If you are afraid that the aquarium heater cover may break down, pick a model with the five-year warranty period. Lifetime warranty is usually useless.

What is the recommended warranty period for a decent aquarium heater cover?

Obviously, it is better to buy aquarium heater cover made by well-known brands that offer longer warranty periods. As soon as your aquarium heater cover breaks, you will not have any problems and should be able to easily repair it for free. On average, manufacturers offer a two-year warranty period for their aquarium heater cover.

What is the optimal warranty period for aquarium heater cover?

Based on our experience, we think that a decent aquarium heater cover should have at least a two-year warranty. There are many expensive models that come with longer periods, but we do not think that it is necessary. Sometimes it is better to buy a new product instead of overpaying for a long warranty and repairing the old aquarium heater cover.
