The fact that this needs to be plugged in the entire time in order for it to work, makes it useless.
Edit:
After writing this request I've received multiple emails from multiple different people asking to "make it right" if I can Edit my review. These are soooo annoying for me. Leave me the f alone. Seriously. I'm not improving my rating or deleting my review. People need to know that this needs to be plugged in, and your ad should be more clear about that along with what type of plug it goes it. There should also be more instructions as to how to install it without wires hanging in front of the window and dash.
And honestly, out of the one star reviews here, mine should have been the least of your concerns.
Hopefully this edit works better than telling the people in my emails to leave me alone. Its going to get worse and worse if you keep contacting me.
