This is a nice collection of sensors for Arduino and RPi applications. There are a few that I will never use but are fun to play with and the ones I will use are of good quality, individually wrapped and come in a sturdy plastic box. If I had to make a suggestion, I would ask them to label the bags better. Some of the sensors are a bit difficult to distinguish. I think it's a worthwhile purchase and would buy from Koeman again at any time.
