It came on my 20' Magnitude and works like a champ. Setup can be a bit confusing, but there's a very good tutorial on Youtube that walks you through it. For a $1 a day, I couldn't find a good reason to try anything else, and being that we use Cricket phones that have some connectivity issues while traveling, having a system on a different network gives us some piece of mind.
