We will launch our new domain name in the fourth quarter of 2019.  In the interim, the current domain name,, will continue being used and therefore the old and new domain names, including but not limited to web pages, products and product pictures, instruction manuals and brochures, will coexist for a certain period of time until the transition is completed.
