not all angel eyes suck.
For years you've been putting up with failures.
It all started with the original DDE with tiny 5W LED that couldn't light up a dark room, then came the massive light boxes with fiber optics, then the relatively fragile CCFL tech, and finally LED.
However at each successive revision, they became more and more reliable, until they culminated with the current Orion V2.
If you are having problems with your kit or don't have one but want ultimate reliability and safety, look at the Orion V2.
