Hello (N) and (M) this is Thomas.
The DCT has taken a while to get to this stage but that is the way of most inventions, trial and error, but in this case the idea of simplifying and making it more user friendly has been the key. There may be other modifications you will make as people get to try it.
More instructions may have to be written as people who trial it come with their suggestions. Belief in the Healing Power of the device will be important to its success. People are used to taking their medicines by mouth or rubbing into the skin. Therefore, the Testimonials page is vital. Customizing it’s use would be useful, a similar idea to gemstones. This is until people have faith in it to bring about magical health benefits!
