input:  Now, answer this question: Title: Back light great, Front WAY too big. Review: I love the Mars 3.0 light, it's super bright, light, tough, and easy to clip.But the Quadrant is way to big, heavy, and cumbersome. I ride in NYC and there's no way I'm going to lug this around with me. Perhaps it's good for riding in the middle of nowhere or calling alien ships (because it is bright), but I ended up selling it and getting a small one.I would suggest not getting the combo. Get the Mars for sure, then something likePlanet Bike Beamer 3 LED Bicycle Light with Quick Cam Bracket Mounteven though the mount is a little finicky. It's just a better setup if you are like me and like not to be weighed down, or leave your lights attached. Is this product review negative?

input:  Now, answer this question: Title: Escort Passport 8500 X50 Review: This radar seems to be super sensitive in selecting its target radar. I received it very quickly in a well packaged carton and installed it the same day. It's been protecting the family ever since. There are very few false warnings in the city. I haven't had it on a long road trip yet but expect it to perform admirably. Is this product review negative?
