After my old Duspol has given up the ghost after years there was only one choice. A new original Benning Duspol. What I like about the voltage detectors is the load connection. Especially with inductive and capacitive currents in the line, so reactive power, you can check this with such Duspols. This happens not so rarely. The instrument can even the savvy electric handyman blindly perform.
The only drawback, which is why only four stars, is the humble probe cover on the cable ...
Otherwise, an absolute must in every (professional) electrical workshop
