R&D capability, manufacturing, tooling design and development, product testing, sourcing, and import and export management are all in-house, so design, testing and export paperwork are handled by the same organisation.

The company welcomes distribution partners in Australia, New Zealand and the European Union and works with Edisyn (Australia) on its website and international digital presence.
