One thing I noticed while using this service (which, again, was pretty much the best thing ever) was that the CMs were constantly having to fight with their tablets. It wasn't that they didn't know how to use them but rather that the tablets themselves were failing, disconnecting, needing to be restarted, etc. If the service continues, I hope TPTB give these folks some improved equipment so that they can do their jobs. Key #4, TPTB! Having CMs trying to hold tablets at a 23.4 degree angle to get a signal before the transportation app locks up is not very efficient!
Also, I purchased the service on Saturday 1/7. On Friday 1/13, it was already not showing on my account & I had to show my emailed receipt for the rest of the day. If you are planning to use it for a full week, make sure to keep your receipt.
