Weaknesses: A little bit too bulky. Coil cord is not long enough. POP may not be accurate. Cell phone signal can confuse it.
Summary: It is better than average, way better than Cobra. Valentine One & Passport 8500X may be better but they cost $100-$200 more. I just need something that is better than average. It has very long range of detection (more than a mile). It has a lot of useful features. I don't like the coil cord (telephone jack type) because it is too short. Sometimes I got a Laser signal when I used my cell phone.
