one of the simplest monitors I have ever installed or calibrated, ran it alongside one aftermarket monitor, and a oem.  really thought it was giving us better info than the oem monitor. like the maps the monitor created for viewing on the go.  couple of downsides, extreme test weight variations will require a easy to do test weight adjustment. and there has been some issues with data download into sms or mapshots, something i'm told they are working on. slingshot account will let you view your maps.
