The video did a great job explaining how to put everything together. It was my second time soldering anything and I was able to get it up and running very quickly. Being the same form factor as the pi 0 makes it very easy to install into your projects.
This is just what I was looking for for running an RGB led lighting setup in our game room. The hardware works wonderfully, the bibliopixel library is great and being actively developed. I even had one of the developers turn around a feature request for the library in less than a day.
I bought the 7 segment kit for a small display of prime numbers. The kit has well laid out documentation and Maniacal Labs responded quickly with the couple of questions I had. I was able to set up the bulk my project before the kit arrived and finish it shortly after assembling the kit.
Well, I love it. It lets you connect strips of RGB LEDs to any processor through USB and control them through Python, and it really does what it says on the tin. Programming them is very easy - I wrote something exciting and fun in a short day, and you can see it here. https://github.com/rec/led
So far no issues, arrived dead fast, and Adam has been very polite and responsive to my no doubt overly spammy questions.
Disclaimer: I knew Adam somewhat from discussing LED strips on the internet before he made these.
