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.

Ex Output:
negative

Huge disappointment that caused nothing but grievances. This TV only lasted 21 days. This Lemon TV quit showing a display out of the blue the day before Christmas Eve! What timing! Guess what I did for Christmas? Not surprised this TV is discontinued. It's a glorified paperweight. Element should stick with making cardboard boxes. I never write reviews but this was a special case. I would avoid buying any Televisions through Amazon. Period. Avoid the hassle and get a name brand TV like a Sony or Samsung. The few extra bucks is worth the peace of mind. Today as I write this, UPS just tried to deliver the same TV I sent out to return for a refund. Didn't bother ringing the door bell with the return label on Tuesday. Welcome to the Holiday Season. Incompetence with both Amazon and UPS. Now I'm going to have to wait probably another week for my refund. If it's too good to be true, it probably is. Buy cheap, get cheap. Just buy a Sony. Don't buy a TV with less than a 4-Star rating and less than 200 reviews. Rule of thumb. P.S. Android is better. Happy New Year!

The batch that I received was permanently affixed to the paper backing. When I tried to peel the stickers away nothing but paper came up behind them. Either way, these are probably not ideal to use on a wall. Based on what I saw I'm guessing that even if the stickers did peel off of their backing correctly that they would not be easy to remove from a wall even if you didn't leave them there for very long. I was especially disappointed because the label said this product was made in the U.S.A. - which I would like to support 100%. The alternative product that I ended up using (it is amazing) was made in England.
