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.

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!
