I have the Escort Redline and love it. I can't tell you how many times it has saved my ass. Not really even realizing I'm speeding until it goes off, I check and realize I'm going about 8 over and slow down just in time to pass the cop car on the side of the road. If there aren't any buildings around, I've had it pick up radar a mile or so away. It scans for K band, KA band and X Band. It also detects laser, but as already mentioned if you're speeding when the laser alert goes off, you just confirmed you're probably getting a ticket lol. It's also supposed to include technology rendering it undetectable. Well worth the price in my opinion though. It's paid for itself several times over.
