School placement delight

Reviewed by: Mrs Margaret Mitchinson - 25 July 2016
A great kit. Bigger speakers that we expected. I purchased 2 of these projects for the two students we had on placement. As we work with electronics I wanted something that they could build that would be of interest to them and also give them some experience of what was involved in this area of work. They were both delighted with what they had produced and it worked brilliantly.
