Second functional prototypes ready for wet-testing

JIT, Just In Time, we made our prototypes ready for sharing them at the NVT meeting in Ede, NL.
These are rapid prototypes, hand polished for the required see-thru property of the AVP device. 
We will soon perform new wet-tests with to learn more about the usability of the whole set, from opening the package until disposal of the set after use.
