Uninformed or unbiased? Thanks for wasting your time having a whinge.
Unless I worked in the industry, I only have BCT's website, annual reports and forums to educate myself. They're clearly going to tell you their product is great and going to take over the world. I've watched the videos, great sell, I've got an order in for some stock. Revenue growth is promising, with a large target market.
I just questioned the acceptance of the end user, whether or not it makes their job more practical. Essentially, this is what will make or break the company, if people want the product. I also like that they could potentially use their product for other purposes, down the track, eg at the vet.
Why do they have 600k debt? I had a brief read but didn't find the answer. My other questions are what is their forecast profit margin, once established, when will they be self funding and require no more CR? I'll continue to DMOR but these are my questions before accumulating any more....
