Well, as a die-hard V1 fan, I have to say the rx65 has managed to impress me in the week I've been using it. I've used my wifes x50 and was always under-whelmed, but the rx65 has been awsome. It is quieter than the x50 and v1, seems to have comparable range and is easy to use.
1. I'm going down highway 271 in Ohio last night and get nailed with a laser alert. I don't know if I was targeted directly or not, but I got a definite laser hit. I didn't get the multiple hits like I usually get on the V1, but it was a definite hit.
2. Today, the rx65 saved me from a nasty ticket by giving me a 1 mike k-band alert to a local cop hiding up a driveway.
I'm impressed so far.
