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 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.

Muy bien! Solo que los cables están muy cortos para medir y en las características menciona que no hay modo de reparación por alguna eventualidad. Es decir que son desechables. Pero aún así son de buena calidad!

Sometimes you don't want to bring out the multimeter just to test the voltage. This is a good alternative.
