My son went to get underglow lights and speakers installed. They half installed the speakers. The volume controls were not ran and the speakers were not set up for his car stereo settings. When we got home we had to work on it for an HOUR ourselves to get them to work properly. The volume controls are now in the back of my sons car where he cannot get to them to adjust them as he's driving. As most of you know, I'm sure, you don't always need or want bass. Well he has to pull over to adjust his bass now. The underglow lights didn't work from day one with the app. They would turn on! But the app never controlled the lights properly. Blue would be red for example. Maybe sometimes. Purple would be green sometimes. And again, as most of you know, red and blue under lights are illegal. So he has NO idea what color he's getting from inside the car. He again, has to pull over to guess around on colors in the app to get a color he wants. Now! One side doesn't even work at all. They're unable to be turned on at all. And last week in the freezing rain countrywide freeze, he had to stand 20 minutes in that rain to even get them to turn off because the app is so faulty. I want a full refund on the underglow lights. I will leave this review al OVER the place as it is my right as a customer share my experience.
