I was really disappointed, this unit is supposed to be LED and ultra long last, after a year, I had a routine message saying that the bulb is tired (really painful) and me laché after 3 years. While doing research on the net, I discovered that it appears that the device failure and that his life was misconfigured, it is that of a standard device that has been registered as my message, but it seems that their customer service refuses to acknowledge the problem.
