A good project that with it's comprehensive instructions gives a very neat looking circuit when complete that was used in a 1/4 scale policebox toy-box project to power the lamp and internal light.

Great, clear and easy to follow manual (sufficient detail even for a complete beginner). The product does what it says on the tin, the quality is good and it gives a neat, small and professional looking circuit. Could only be improved by giving fault finding info in case you run into problems.
