Grayling has been attending numerous conferences & trade shows http://www.clearcalm.com/news_events... and have placed units out on evaluation. The feed-back was universally extremely positive. This was one of the reasons for my investment. My concern is "Where are the orders?". The lack of information regarding orders and what I must assume as the failure of the sales and marketing end of this organization causes me great concern. I must assume that there is something that they are not telling us.
