We are going to demonstrate the best garage door opener in the United States. We will compare Chamberlain (sold at Home Depot and Lowe’s) to our garage door opener which is made by a German owned company in China, sold in Germany, Australia and South Africa. Dealer and Manufacturer Rep inquiries welcome. Our garage door opener is the most quiet and safest mechanism on the market. Contact M Smith, 214-257-8300 for more information.
