I will tell you this, Never buy from US AMPRIME TECHNOLOGY. I wanted to return as my tractor does not have a cig lighter to plug monitor into. This company has sent me 6 different emails, requesting me to take photos of box contents, photo of tractor, hook up camera and send photo of what is on monitor and they keep going on and on, hoping I will give up. Lucky for me I bought thru Walmart, Walmart has read all emails between me and US AMPRIME TECHNOLOGY and assured me I would get my 108.00 credited back to my cc. and said they would handle it from here on out, told me not to worry about it. The product was a Prodofo backup camera.
