Big thumbs up for the product itself, and the customer service.
Product-wise, if you own the Norte-Dame set and are on the fence about lighting it... just do it! The build itself was already beautiful, but it really comes to life once it's all lit up.
As for the customer service, I know there are a few other competing light kits from other companies, but from my experience, I'll be sticking with these guys... A few weeks after installing the lights, I needed to move the set, and in doing so mostly likely damaged a small piece that connects to a USB socket to light it all up. After filling out a quick form, they'd sent out the replacement pieces free of charge, and from AU to NZ within 2 days flat! 10/10
