Summary: I bought a new item. First one broke within 15 minutes of installation. The replacement was second hand, smelt of smoke and was the wrong item yet packed in the right box, with seals! The third one is installed and working well. A great piece of kit when it works.
Summary: Got one from CDON about 2 weeks ago, not happy with it. It start to get the annoying coil whine, not very loud but noticeable. For the price I paid, I am a bit disappointed. Just contact CDON, see if can get a new one.
