XDSL does, indeed, have some products that are selling.
However, the quantity of these being sold is small. It is also unclear that these jumpstarter products actually use any of XDSLs patented technology. We have no knowledge of whom it is that is manufacturing the jumpstarters for them,....
And it doesn't change the FACT that the company has billions of authorized shares, is saddled with a large quantity of shares constantly being dumped into the market via convertible debentures, and despite the fact that the company has close to nil in income - the execs draw large salaries.
So - what I am saying is,..... if you want to take that risk - going in with both eyes open,.... more power to you.
But if you expect anything but more of the same from these guys - you are setting yourself up for disappointment and for a financial loss.
