[Q]: 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.
[A]: negative


[Q]: Terrible customer service, at first my safe was supposed to arrive on the 5th, then It was the 8th, then the 14th, and now I'm being told I have to contact the shipping company to find where my order is??? DO NOT BUY FROM THESE PEOPLE. I also found out the they just bought it from Wal-Mart and had the shipping company pick it up. I could have just drove to Wal-Mart and bought it myself to save all this headache!
[A]: negative


[Q]: I never received my order. I emailed several times, was told that it was damaged in transit and was asked whether I wanted a refund or a replacement. I requested a refund but have not received it. Instead, I have received several emails asking for pictures, for details about the damage, and have received no resolution.
[A]:
negative
