At 5 bucks a month and no minimums that seems to be a good offer if you only want to monitor a few wide formats, right? But if you have a fleet of 500? That's $2,500 per month. I understand that not every client will want the monitoring.
I'm out in the street every day, and probably the biggest complaint I get from clients is that they can't have more than one toner of each color on hand, I hear this from net new prospects also.
This is a good fit for wide format market place, and I can see the need when clients are running heavy volume.
