I've had nothing but problems since I've switched to the Redline. Now within two months my sound failed and I almost got a ticket, was really lucky I saw it blinking.
I'm just glad I bought it from Amazon, because even though it was past the return date Amazon forced Escort to take it back after calling them.
I'm going back to a V1, my old V1 lasted like 5 years with no issue. Seems like Escort just doesn't have what it takes to make a quality product, and their customer service skills are nonexistent, everyone I've talked to was rude and not the least bit surprised their product is failing. Radar detectors aren't a complex technology, there's no reason why Escorts are failing so rapidly for so many people.
