My son and I have each had one for about 3-4 months. They are great except for one fatal flaw. The LCD screen is extremely vulnerable to breaking. If you get one, treat it with extreme care. I would not recommend Jogging, etc. If the screen breaks there is NO way to replace it. The ribbon cable that connects it to the main board is hard soldered with about 50 closely placed points. There is no connector. Needless to say I found this out the hard way. It would have been nice if they had put a connector for easy replacement. As it is if the screen cracks you might as well toss it.
