Installed today and found the test lamp doesn't work at all which I've tried every way I can but no luck. Thank goodness it still has power when I plug in dry hair. When trying to assemble, I have another problem with cheaply made screws, as my screwdriver will damage the screws when attempting to assemble. I have no issues with seams made in the USA. After these two problems, I have to decide to get one locally at a home camp that will solve my problem. Hopefully they can improve quality control with better screws.
