It is a very sturdy unit with dimensions that make it look like it was designed for this truck. Klassisch und gut für einen langen Tag im Büro ohne Abends schmerzende Füsse zu haben. I’m charging my light with a power bank because I don’t want to remove and attach the light. Están súper. I know it comes with 10 different adapters but why not just make a model for each brand instead of giving me 9 pieces I don’t need? Problems: if you tend to have swollen ankles, they are a little tight around the top, and theres very little padding in the sole - they are more like a neoprene sock than an actual slipper. I will be returning mine for that reason. I called Chaco about this concern, and they confirmed their design is now different. I highly recommend NRG to anyone wishing for a quality sound experience on their Apple device. I already threw away the screws and anchors provided.
