As most reviewers have written, this is a really good starter kit for hobbyists who want to explore a variety of sensor modules. You don't just get sensors - sensors are mounted on boards with supporting circuitry. One reviewer complained about the lack of jack-to-jack connectors. This is only a problem for connecting to Raspberry, not Arduino. There are many male to female connectors available for the Arduino, although I don't know why this set needs the male to male connectors it has. Each small module is packaged in a small resealable plastic bag that can be tagged for identification. I would use a tackle box for storing small modules and a kit container for larger components. The one major complaint that many reviewers have had is poor or missing documentation. I think the folks at SunFounder listened because the kit I received came with a little booklet that clearly defined and explained each module. It also includes projects for each module (which I haven't tried yet). While this documentation is not perfect, it is much better than the online documentation available at app.box.com.
