Escort Radar EU

hello! I purchased an Escort max 3 international device from you and was very disappointed...The Iskra-Video police radar, which works in the K-band, does not react in any way, but it works on all the doors of gas stations and shops! There is no support in the form of updates for the international version at all! 2 updates were released for the American version and none for the international version... I'm sorry for a lot of money wasted-400 euros and unjustified expectations! Before that, I had a radar detector from a Korean manufacturer in 3!!! three times cheaper and who always warned me in advance about police ambushes! Please release at least an update for the international version that will improve the work will respond to the Iskra-video radar used by police officers in my country...
