My experience purchasing at the QuakeHOLD! online store was less than satisfying. I was hoping for a better one. My expectations were not met, despite the fact that they promised to provide me with high-quality goods and first-rate support. The prices were fair, but the quality of the products I obtained did not live up to the claims made about their superiority in the product descriptions. In addition, the customer service I obtained lacked professionalism and did not address or address satisfactorily my concerns. I'm sorry to say that I can't recommend purchasing at QuakeHOLD!, but I would suggest looking into other options if you have concerns about the safety of your house.
