Installation took a long time. The instructions were great and they even have a YouTube video to help set it up. But the installation took me a good 2 hours. My fingers are quite large, so I had to spend extra time on them. Overall very good and very nice. Got this for my autistic son and he loves it. The big downside, however, is the battery life. You'll miss out on about an hour or two of battery life because of the light show.
