My feeling about this device is, that you may want to utilize it for
your own use but regardless of what you or Jim ultimately experience,
I don't think it would be a good idea to provide, recommend or depend
upon this device in the course of business. It's likely that it will
work some or most of the time under some conditions but ...... not
every time ..... without fail.
