So far I am really impressed with this camera, works great with my Motorola phone. Has a clear image and does exactly what I need it too , checking bore for copper fouling. Compact enough to take with you to gun shop or gun show to check bore condition. The camera part is much longer than any of my rifle barrels so that's a plus. Only downside I have found is that my phone case must be removed in order to plug into phone . Not a deal breaker by any means. I like that you can take photos and videos with the camera.
