To Our Current and Future Customers:

We have become aware of counterfeit and other unauthorized products that illegally bear our trademarks [including Grover® and Rotomatic®] that are being manufactured and sold by unauthorized resellers who are attempting to unlawfully imitate our products. These products are not authorized by us and infringe our valuable intellectual property rights while harming unsuspecting customers who purchase them since they are not our genuine merchandise and are not covered by our warranty. We are committed to selling only high-quality products that undergo rigorous testing and exceed industry standards for product materials and integrity to ensure their long-lasting functionality, quality, and reliability. However, we cannot assure that these imitation products will meet such criteria, and we do not accept any liability for failure, defects or damage caused by them.

We are taking active measures to identify and remove these imitation products from the global market. We also welcome reports and information regarding any such products, which can be sent to us at [email protected]. In addition, if you have purchased what you believe to be one of our products, and you have questions as to authenticity, please contact us at the above address. We value your assistance in our campaign to protect our customers from confusion and dissatisfaction, and we urge all purchasers to be mindful of this situation and strongly advise against purchasing products that are believed to be ours at suspiciously low prices via other unauthorized resellers.
