I haven?t had any issues so far. BLM! Even as the weather turns colder I?m still wearing around the house. So it was easy to install and has at least worked for two or three weeks? We moved in March 1 and ordered it about a week or so later. (It was only a $10 difference for me here so I went for it). Usage was easy and intuitive. It is a true spot beam, and light is visible a half mile down the road. Its not flexible enough to fit around certain things like stair railings and certain types of fencing. They fit true to size, order whatever shoe size your child or yourself are currently wearing. They are lightweight, and the sizing was perfect, just make sure you measure your kiddos feet and then check the sizing chart to get the correct size.
