Moin, Had two NG ordered on 01.05.2015 and got them within the specified delivery window of about 20 days. The parts arrived in a padded envelope. First visual impression, the device is very compact and the connection terminals are of decent quality. Now for the functional testing, - for me is important, which is the residual ripple of 24 V output voltage well. Had experienced at saving LED bulbs with power supplies of a large company a real bankrupt when changing halogen lamps. These power supplies were not suitable for my purpose, because all LEDs flickered. I wanted no disco, but I wanted to have my countertop evenly lit in the kitchen. The supplied Lerway LED lamps 24V 1A 24W AC / DC power supply unit fully meet my needs and that. Without hum noise I'm very satisfied.
