Well the Escort Passport Max is going to be returned...
There appears to be a mounting design flaw on their bracket ( think diving board with a heavy person on the end of it ) where the radar detector (which is pretty heavy btw) bounces and eventually separate the housing / casing near the rear by the lens. Eventually after a week or so the detector falls off from the mount. As far as detection performance goes it was excellent, much better IMO compared to the V1 as far as false alerts and I love how the passport max locks out and stores all false alerts and automatically mutes them. However, I prefer the V1's quality constructions versus the cheaper plasticky construction of the Passport Max.
Here is a video of what I am talking about..
