Refund Policy

All frequency generators are sold with a 60 day Money Back 100% Satisfaction Guarantee without any restocking fees as long as products (including MOPA Amplifiers) are in new condition with no scratches or other marks.

GB4000FrequencyGenerator.com may, but are under no obligation to, honor requests for refunds for the following reasons:

Non-delivery of the product: Due to an issue with the mail or courier service, you do not receive a delivery e-mail from us. Depending on the price of the product, GB4000FrequencyGenerator.com may require you to first submit proof that you have submitted a report to the mail service or courier company describing the missing item;

Download issues: Our products are not downloadable they are physical items so this is not a valid reason for a refund. If you have problems that prevent you from downloading anything from our website GB4000FrequencyGenerator.com recommends that you contact the support team for your browser provider, as GB4000FrequencyGenerator.com ensures that our software can be downloaded with all major browsers, and this problem usually arises from a customer’s issue with either their browser, firewall, or network;

Irreparable defects with the software: Although all the products are thoroughly tested before release, unexpected errors may occur. This reason should be submitted to our Support Team for its approval of your refund request;

Product not-as-described: A request based on this reason is addressed on a case-by-case basis and subject to our approval. To prevent this kind of claim from arising, every customer is encouraged to check free samples ( in the form of video overviews, demo links, product samples, screen shots) of each type of the product offered before making a purchase. As long as it is within the 60 day satisfaction guarantee we will honor the return. We want you to be happy with your purchase!
