Since the beginning, our idea was to offer the highest quality tDCS device for people interested in trying it as an alternative treatment. We have worked really hard with lots of vendors for the roughly 1 1/2 years we are operating to keep our quality high. Because we started with such a robust design, we have not made any significant modifications to it for that entire period. Our customers continue to be satisfied with the quality of our product and our return rate continues to hover below 1 percent after thousands of units sold. That is saying a lot about our philosophy at ApeX Electronics. We cared about our customers; we created a system we believed was the best at that time. And since then, nothing changed. So our device did not have to either.
