We aim to deliver \r\nproducts twice as good as our competitors at a fraction of the cost of famous \r\nbrands. All Rockville products go through the most rigorous quality control \r\nstandards in the industry. Products go through months of extensive testing \r\nbefore they reach your hands. All functions and components are tested for \r\nquality. Rockville makes products that are virtually un-breakable! Rockville is \r\none of the only brands in its class to have engineers and technicians test every \r\nconcept model for weeks or months before starting production. Once production \r\nbegins, Rockville sends product engineers to the factory to quality control \r\nevery product. After production is complete Rockville has the head of QC in our \r\noverseas office test a certain percentage of all products from the production \r\nline a second time to ensure that the quality meets our strict standards. All \r\nRockville products are backed with a hassle free warranty.\u003c\/font\u003e\u003c\/span\u003e\u003cspan style=\"font-family: Arial;\"\u003e\u003cfont size=\"3\"\u003e \u003c\/font\u003e\u003c\/span\u003e","brand":"Rockville","offers":[{"title":"Default Title","offer_id":46935861100845,"sku":"(2) DESTROYER 12D1","price":694.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/0805\/3037\/products\/b1acd5c7-fb06-4ad8-b80b-f3729b9faad7.jpg?v=1702534118","url":"https:\/\/audiosavings.com\/products\/rockville-2-destroyer-12d1","provider":"Audio Savings","version":"1.0","type":"link"}
