Example Input: Received this “Auto Vox Digital Wireless Backup Camera” in a timely manner, installation was very easy. Took me approximately 1 hour from start to finish to complete the job. However when I first tried it, it worked but there was at least maybe a 5 second delay and I thought I could live with that. The picture was very clear with no interference, and that’s where it ends. When i got into my truck to head out, I put it in reverse and nothing! I spent several hours trying to relocate the transmitter and hardwire the wires to my backup lights. But nothing worked.
Example Output: negative

Example Input: Well this stuff was crumbly and would not stick to itself. It was like wat sand. I couldn’t knead it or work with it at all. Added water and pushed it in the mold and it cracked in thousands of pieces. Worthless stuff don’t buy it.
Example Output: negative

Example Input: We bought this to hang up webbing for Halloween decorations. We thought that since web is light and we were sticking to the stucco it would work perfectly ... not so ! Everything had to be redone the next day :(
Example Output:
negative
