I'm a Valentine 1 owner (3.813)...but I don't see why you guys keep spending your hard earned money on this latest version (3.856)...which has obvious Quality Control issues. It is so well documented that the "E" problem needs to be addressed and solved by Valentine.
While I have been extremely happy with my 3.813, when looking for a Radar Detector for my second car...I refused to even consider the 3.856.
Due to the above reason, I just ordered the Escort 8500 X50 (6.1) from Roy.
When Valentine finally acknowledges this Quality Control problem and resolves the issue, I will probably return as a customer. Maybe you guys should do the same and quit complaining.
