Bought the Smarter kit, expansion packs, and equal Screw mounting kits for each panel 2 years ago. A month ago the controller died. After back and forth emails for a month Nanoleaf wouldn't replace under warranty, or even sell the controller as an individual replacement part. I would be forced to buy a new Smarter kit just to get my lights working again, or have to pull them off the wall and repair all the damage the screw mount kits did to my walls.
Not the life span I had imagined for an LED light.
