After taking my time unkinking the lines and eyeballing routing of the wires and positions of the strips, it took me around 4 hour to mount the strips, route the wires so they were hidden, download the Smartphone App, and get the lights running.The footwell lights are so bright that I had to adjust them down a bit. There are also lots of different lighting patterns to experiment with on the Smartphone app.

The Good-
Completely changes the feel of the car. Looks great.App provides TOTAL control of the lights. So many possibilities of different colors and sequence of illumination it's virtually unlimited. My head is spinning ??????.
Installation - Much difficult than I thought. Recommend laying all the lights out and finding good surfaces to attach to. Ensure the wires reach and can be hidden whenever possible for a clean look.Check that lights light up, wires reach, and hide wires before attaching LED strips to car.
The Bad-
App - There are a couple of different options for download so it's not crystal clear, but still not too hard to figure out.

Summary-
Truth be told I would give a 4.5 if I could but decided to round up. I actually already recommended this product to my wife so there you go. I'm putting my personal safety and well-being on the line to recommend this product to others.
