We deployed about 400 units early this year at Chicago Messenger Service. They seem to be working well....They use the MC65 with an Agilis application for proof of delivery. they also use the devcies for voice communication. The drivers are carless at best with the handling of the devices The AE on the account os Paul Czerwinski...if you want to set up any kind of customer to customer contact he would be the person to contact I would advise in advance that the contact person at the customer has an unpredictable personality.. Although the devices are working, you never know what she will say
