I'm on my third one of these. The audio on the first one failed after around a year, and RS replaced it.After 4 months, some of the LEDs started flickering, and over a few weeks, most of them stopped working altogether. RS replaced it again, and lent me a second hand one while their engineers checked it. One of the lights on this also flickered. They eventually decided mine was unrepairable, and replaced it again.Six weeks later, the linear light on the latest one has started flickering.Looks as if this is a common problem. A pity, because otherwise it is great value.
