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

This brush is a snow and ice BEAST! It is, perhaps, the most solidly built brush and scraper, with easy extension and easy rotation of the brush to change its angle relative to the shaft. As it is a new purchase for me, I'll have to update this later in the snow season. And, frankly, I'm hoping that I won't need it again this season. But I am prepared! Fast shipping, and excellent follow-up by the sender. highly recommended.

Ex Output:
positive


Ex Input:
I was really disappointed. My daughter had been asking for this so I wanted to surprise her. I opened it when it arrived and was mad to see that it had CLEARLY been returned from Christmas. It was only the stand. All the surprise pieces were gone, and the handle wasn’t even included. The green from a Christmas tree were scattered inside it. Customer service didn’t even reach out to me when I requested a return stating what happened.

Ex Output:

negative
