mort,.... you sound a lot like I did about this company,... about 4 years ago. I was similarly optimistic about the technology they were exploring (the wettable surfaces in their batteries and other applications that their R&D group appeared to be exploring).
I have soured on the management - although I think the tech is still worth something in the right hands. Just don't think management is that right set of hands. I got out about a year ago with a fairly small overall loss and while I continue to watch, I haven't seen anything convincing to get me back in here.
The current product - the jumpstarter - does seem to be selling at a better clip than did their previous attempt (an overpriced flashlight). However - the revenue is nowhere near what they need to keep the lights on and the CEOs paid.
So - lost of convertable notes, and some big share sales continue. They don't look to be slowing up share sales any time in the future. Don't bet the farm - trade in and out as their shareprice allows you to make a profit,... but don't expect much.
