## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Good quality & well featured.
  

*by M***N on Reviewed in the United Kingdom on May 4, 2015*

This is a really good piece of kit. Powered by 3 X AA type 1.5 Volt batteries, it has both an audible & visual indication of continuity depending on which terminals you use for testing. The visual is a super bright LED which also doubles as a useful torch with a switch on the side of the unit. The unit responds quickly to a short circuit being applied to the terminals which is not always the case with some multimeters on continuity test. The conditions are 0-20ohms for visual indication & 0-250ohms for audible.  Also there is a non-contact LED which is useful for tracing AC mains.(There is a fold out wire "antenna" which makes such readings a bit more precise. Additionally, the unit, although intended for powered down contact/continuity tests, claims it is protected from external voltages up to 300volts AC/DC for a maximum of 30 seconds. I've not tested this yet but note that there is a 3rd LED on the unit which seems to warn when this occurs. My only slight disappointment is that the 3 input terminals appear in the picture to be the type that take both the usual 4mm test leads (which they do) & have the possibility of tightening them onto bare wires too (which they do not) Overall very pleased with just the one slight reservation.

    gutes Gerät mit einem Fabrikationsfehler

Testboy war schon immer gut, doch der neue 20 plus ist noch etwas besser geworden.Wenn Sie sich auch einen Testboy 20 plus kaufen, werden Sie feststellen, dass er nicht funktioniert. Dies liegt daran dass die Prüfdrähte keinen Kontakt bekommen. Die Schutzisolierung ist leider zu lang geraten. An den Steckern zum Gerät die Schutzhülle um ca. 10 mmmit einem Messer kürzen und das Problem ist behoben. In diesen Hüllen stecken Stopfen welche zur Abdeckung der Prüfspitzen gedacht sind, was sehr sinnvoll ist (Verletzungsschutz).

    Einfach schlecht.

Das zuerst gelieferte Gerät ging nur teilweise (Phasenprüfer und akustische Messung), beim Austauschgerät ging nur die Taschenlampe. Das ist unterste Schublade. Gerade in diesem sensiblen Bereich sollte es Technik 100%ig funktionieren, ist ja nicht ganz ungefährlich.
