The Nanoleaf system should come with a warning sticker on the box stating that this product is addictive.
It's a very simple system to put together, but the way it works is amazing.
I love how even after you've had some panels in place and then add more panels the controller is able to find new panels, enrol them into the system, and map out the new layout.
After hanging a couple of panels you'll get used to putting connectors in place without removing the panel as you decide that you'd rather have a line go off this way instead of that way.
As another reviewer mentioned, it would be nice if the expansion packs prompted a quick check for the buyer to calculate the number of power supplies required.
Wasn't a big issue as the controller seems to determine how many power supplies there are in the system and then determines how many power supplies are needed and then sets the maximum brightness so as to not overdraw off the existing power supply(ies). Just sucked having to wait a couple of weeks to get my display back up to full power.
I haven't played around with creating any patterns yet, but that will probably come soon enough.
The only wish that I have is that it would be nice if the controller was able to accept a USB connection so that it could be fed audio directly from a computer.
Barring that, the microphone inside the controller seems to do a very decent job with the low audio levels from my computer in my apartment.
