Wireless Endoscope, NIDAGE Upgrade 5MP HD WiFi Borescope 1944P Semi-Rigid Snake Camera with 2200 mAh Battery for Android and iOS Smartphone Tablet Automotive Drain Pipe House Check(33FT)

Unless I am missing something, having a 1944p camera without a focus ring is like having a Corvette sitting in your driveway without wheels, looks nice but pretty useless. I have tried this unit between floors of a house and in pipes and I have yet to have a usable picture. I'm disappointed.

Great quality and great price!
