Honestly I was very skeptical that something this simple in appearance and at such a low price point could work as effectively as it does, especially as a first generation product. In terms of ease of setup and use I think it can't get much better considering how comprehensive it is in terms of the level of control it gives you. There are some areas which need to be worked out like the way "shared" devices (such as an Apple TV) are setup; right now if I set a limit to cap my kids, there is no easy way for me to bypass it when I want to watch something after they've gone to bed. Also the cumulative time limit functions have a flaw if you have devices which generate a lot of "background" Internet traffic; they area aware of it and state they're working on a solution. As long as they keep updating the features regularly I think this will be a very successful product with families.
