STRONG ENOUGH, To survive in the most harsh environments.

SMALL ENOUGH, To make each space most effective.

SURE Electronics will be transformed into a professional designer and a manufacturer of Class-D audio amplifiers and matched power supplies. So SURE brand will fade away from retail and Sure Electronics will be committed to provide solutions, instead of direct products, for our distributors and partners. Our company name, Sure Electronics, will always remain the same.
