Of the 3 treads I recieved, 2 of them werked well. The 3rd one worked for about a week and stopped working. I found a black scorch mark on the step, under the tread where the connection was made. After that the GFI would not stay set. I think there must have been a defect in the tread or the connector. I have yet to contact the company about this issue as it is spring and it not needed.
Hi Steve, Sorry about the issue and thanks for the feedback. We have just followed-up with contact information to arrange for a return.
