I purchased this 6 months ago. Today the "eye" is dead. After 3 hours of customer service they wanted to send me a new unit. GREAT until you pay MORE. Also beware that the warranty is just that. They do not care if the unit dies in the middle. I also do personally have a problem that they want to charge you and the person on the other end giggles and you have to repeat the information 4 times. Save yourself the trouble and stay away.
