Our warranty covers all defects in materials and workmanship for all products sold and manufactured by BH. Only original, unaltered, and unmodified materials and workmanship are 

covered by this policy. This warranty does not cover damage caused by improper deployment, misuse, accidents, neglect or the natural breakdown of materials over time. Products should be returned to us for evaluation. Items with defects in materials and workmanship will be repaired or refunded.

If the product's warranty period expires or the product has no warranty, we can still repair it for you. In such circumstances, you should bear the cost of maintenance and transport of the product in the real time processing. 

In the event of discontinuance of product manufacture, we will provide a maintenance service if the product has any quality problem within the warranty period.
