I've been an Adafruit customer for years and rely on them for best in class DIY, maker, geek, Arduino components and support. They develop and support their own leading edge products, and seem to have an inside track on Arduino products, as well.
Support has been excellent through their online forum. Returns are handled quickly and without fuss, also through the forum and email. They have a generous return and credit policy.
Do not expect detailed instructions or handholding to accompany these types of products. All product information, instructions, support, help, guidance and ideation are online. Adafruit has plenty of videos, learning materials and their online forum to get you up and running, but it's up to you to look for help. This is maker-ware.
