Review on Wireless Endoscope With 50Ft Borescope, WiFi Inspection Camera 5.0MP 1944P 6X Zoom, LIMINK HD Waterproof Sewer Camera With Light, Pipeline Endoscopic Snake Camera For IPhone, Android & Tablet by Jake Meyer

I was hesitant to purchase this product after reading the sparse reviews but am so glad I did. I suspected that the connection issues might be user issues which I think is true. The phone app was perfect and easy to use. To connect wirelessly, you have to turn off Auto-connect for the wifi you use at home. That way you can connect to the endoscopy easily, so easily that even when I returned to use the camera another day it connected as soon as I opened it the app.As for the "no picture" complaint, I had what I thought was the same issue. When I pushed the camera into the pipe I couldn't see anything. However when I pulled it out of the pipe I could see the video. Hmmm, I thought. So I pushed the camera in a few more feet and Voila! I could see the video. It turns out that the interior of the first few feet of the pipe was black so there was nothing to see, just blackness. I'm glad I didn't give up!My only "complaint" is that the light is not really adjustable. When I adjusted the brightness it was pretty much either on or off. This fact did not affected the usefulness of the tool for me.I did not try to use the camera without taping it to another object. I think the cable is too flexible to be effective in a long run of 4" pipe. I taped it to a garden hose at first. This proved to be difficult to push into the pipe at about 30 feet. Next I used a fiberglass electrical wire-pulling tool. That was much, much easier to convey into the pipe.The only "problem" you are going to have to overcome when using this tool is how to protect the camera and keep it somewhat centered in the pipe. It is such a small camera that if there is any water in the pipe it will submerge and you won't be able to see. I inserted the camera in a 1" PVC coupler with some spacing material and taped it in place.Lastly, I did not have any problem with the battery. I fully charged it before attempting to use the camera. I used it for more than an hour over a span of four or five days and never ran out of power.I am pleased to own this useful and inexpensive tool and look forward to finding other uses for it.
