Gutter Helmet offers to resolve any clogging or gutter issues for the lifetime of the product. Calls to the company requesting service for issues generated empty promises and no service calls. Confronted the Sales Reps at a local home show in the midst of their spiel. They made a show of telling me they would get help as soon as possible, same results - nothing!!! User's recommendation: Check existing customer references to see if they live up to their claims.
