The lights themselves are fantastic overall. But in order to set them to anything other than regular driving mode, you have to use the JW Speaker app, which is abysmal. Not only does it make you log in every time you use it (good luck changing the settings outside cell service!), but you have to navigate a maze of options before you can change the settings, and each headlight is controlled separately, so you have to do this TWICE. The shop that sold this to me had no idea how bad the app is until I showed it to them and said they're not going to recommend them anymore.Edit: Upping my review by a star since the app now lets me control both headlights at once.
