Review on Feisike Handlebar Function Adjustable Rotatable by Gerardo Goodson

I rode my e-bike 30 miles in all road conditions. In traffic jams where cars are driving at normal speed, the camera is basically useless. Vehicles are not visible until they are directly overhead. The only environment where the camera is useful is in very heavy traffic at 10 mph or less. The camera has a viewing angle of 195 degrees. When the vehicle is 100 feet behind, this extreme angle makes it look like an almost invisible point. Everything within 10 feet is clearly visible. But when you're stuck in a traffic jam, it's very important to see the cars that are approaching you. You really can't see them until they're directly overhead. I have yet to use my review mirror. Don't buy this.
