Okay, I originally bought the first set and had them installed unprofessionally no problem. After a couple of days I noticed condensation in the headlights (common issue) ,but always prepare to re-seal headlights prior to installing in order to assure condensation does not happen again. I then had the warranty replace for new ones and got those installed, professionally this time, and never been happier. You get what you pay for which is quality! Had them for a month now and they are beautiful!
