A quick and easy repair at lunchtime today. This gadget contains ultra-violet light tubes, and the user puts their hand under these lights to set their nail varnish... or something along those lines! I wasn't aware such things existed until it was brought in.

The fault was caused by a combination of poor design and the owner's neatness. We've probably all done this at some time - wrapping the cable tightly around the bit of equipment. This will often cause the cable to break just where it goes into the case, at the point of most stress.
