Ratings and reviews

No Longer Works! I am using a fully updated Samsung Galaxy S23+. The app has been updated, un-installed, re-installed, and all permissions have been given. This app and borescope worked about a year ago when I used it last, but not anymore. When I try to click the record button, an error message appears saying "No ET16 Connected". When I try to modify the USB connection settings, the control will not switch control modes. Still waiting for support to get back to me.

Not bad, ran into a little problem when I had the scope plugged in first and the app not picking it up. All I did was unplug it, then plug it back into the phone with the app already open. Connected right up and was good to go! There may be a manual that originally came with it that probably tells you that, we bought it at a garage sale for like $20. But it's not needed, just download the app and plug it in, and your good to go. Minimal knowledge or experience to use.

For the price, it was a good deal. I used it three times, located a leak oregin in my roof, and repaired my roof. I tried the device again to check a buried ball valve, and the app kept shutting off and restarting, making it impossible to use. I am using it on my android phone. The app has full permission to use the camera. All other settings are as needed and updated on my phone. I am thinking about returning it if I can't get it to work.
