I've just joined your interesting forum and i'm really impressed by quantity and quality of valuable information you share here. Speed fines here in Slovenia are among the highest in Europe, so a RD is a worthy investment. Just for testing I started with my first RD - used Bel 990i and it works as promised, so after this positive experience i'm contemplating something with GPS and possibility to block false alarms. Seems i've come to the right place.
Will ask for details when i finish with usual FAQ.
