About Rockville Quality Control Procedures:
The
Rockville brand stands for Quality, Innovation and Value. All Rockville
products go through the most rigorous quality control standards in the
industry. Products go through months of extensive testing before they
reach your hands. All user functions are tested and all internal
components are tested for quality. Rockville makes products that are
virtually un-breakable! Rockville is one of the only brands in its class
to test every concept model for weeks or months before starting
production. Once production begins, Rockville sends product engineers to
their factory to quality control every line of production. During
production every product is tested and on top of that Rockville goes the
extra mile and has their high level product engineers do an additional
quality control. They test a certain percentage of all products from the
production line a second time to ensure that the quality meets their
vigorous standards, and to make sure that there is never a batch of
products with even a slight problem. All Rockville products are backed
with a hassle free warranty, though it is unlikely that you will need to
use it.
