It is absolutely necessary and perfect.
This voltage tester was a must have for me. I feel more at ease putting my trust in this product than I do a voltage pen, therefore since I lost my previous tester I purchased this affordable one. Absolutely perfect for checking safe isolation and betteries. Very please with this handy pocket tester.

Small and handy
Small and compact, can easily have in a pocket or small pouch. And the addition of no batteries required means less maintenance, the low price also makes it very affordable to replace should it became damaged or faulty. However I doubt the latter as klein is know for quality tools.
