I currently have an Escort 8500 x50 and it works great for me. I am thinking of getting the 9500i since it has the GPS to lock out false signals, which I get quite often on my x50. I have heard people are returning them and the lock doesn't work correctly. My question, how is the escort 9500i compared to the x50? Are there any bugs that needs fixing on the 9500i because I am really thinking of getting it. thanks for any type of reply.
