I see positive and negative reviews. Most of the negative reviews are related to the color and usage. The red is very bright. The blue is subtle and can be used in a dark room. As for in-car use? I would not recommend traveling with him. If you want to use it in the parking lot. Red is best for outdoors and blue/purple is best for a dark room. I personally like red. Don't expect movement like in some videos. In order for the lights to change pattern, you have to do it manually. Coverage is adequate, while many lasers don't emit enough light (red). It was definitely brighter than the ones I bought on ebay.
