I used an Escort Redline for a few years about a decade ago. While it did save me a bunch of times, the false alarms simply became too much and I got rid of it. It made driving more stressful than speeding without it. If it were fail-safe, I'd be all for it. But all the noise, mostly false alarms, and not being of any use with lasers, I just didn't think it was worth it. Since I got rid of it, I enjoy driving much more, whether speeding or not.
Pros: saved from tickets
Cons: too many false alarms
