I bought 2 of these for our master bathroom renovation. Within months of using, the lights on one of the cabinets no longer worked. The second one worked for about a year and now on the lights on that cabinet don't work. Customer service has been helpful and sent me a replacement transformer and wiring assembly for one of them, but in my opinion the wiring connection to the door is poorly designed. It cannot withstand the continual opening and closing of the door over time.
