I have the nanoleaf canvas kit plus expansion pack and have loved the product since I purchased (in fact I just purchased a second full kit of the same product) when one of the squares started malfunctioning I was hesitant to contact support I figured they would give me a run around or charge me for shipping me any replacements, make it difficult to replace the square that didn't work. Nothing can be further than the truth they got back in a prompt manner gave me steps to test the defective item and when it was clear it couldn't be fixed at home immediately sent me a new one with no hoops to jump through I was thoroughly impressed great support to go with a great product.Good job!!!!
