I purchased the iball hitch camera. I wanted to get a camera for hitching my trailer but also for viewing the inside horse area of the trailer while driving. Pony cam! I search and read reviews. A lot of them were quite complicated looking and the price tag...pretty high. Plus not all had the ability to do both functions.
Introducing the iball camera. It is magnetic and sits near the ball for hitching. Then you can move it somewhere in the interior of the trailer to view what ponies are up to. The price was about $149. I was very pleased. Using it the first time meant that hitching was a breeze. I just had to figure out what view showed the proper alignment. I'll be able to hitch up myself and in a flash!! I was so excited that I literally jumped up and down for joy when I came out to see the ball perfectly aligned.
The screen that you see inside the truck just simply plugs into the charger (cigarette lighter). The only issue noted is that having devices with Bluetooth on will interfere with the picture. I rarely use Bluetooth on my phones so not worried about that. I am always happy to find a good deal on a product that actually works they way they say it will! I definitely recommend this camera!
