For the price, excellent
Purchased as replacement item. Had one before but dropped it. It did not survive

It's okay,
Instructions need to be on a bigger piece of paper, why so small ? Otherwise not bad for apprentices who are learning for first time. Also a belt clip on all units would be better for accessibility when moving about on construction sites. Send me royalty for idea when you sell thousands as not many manufacturers have them.

per quello che costa è davvero tanta roba. Vediamo solo quanto dura.....

Worthwhile
The plastic body is cheap plastic that could break, but the feature set is huge. I could not find another product with all these features for less than double the price ($300). Update 2021 May: Been using this for a year. Still works as designed.

Perfekt
Der Tester ist sehr gut. Plus: + Fehler lassen sich schnell aufspüren. Hatte einen Kabel-Fehler. Der Fluke-MicroMapper zeigte gar nichts an. Der AT278 zeigte an, was (Kurzschluss zweier Drähte und Unterbrechung eines Drahtes) und wo (Leitungslänge). + Anleitung auf Deutsch. + Aufbewahrungsbox + Preis/Leistungsverhältnis ungeschlagen Minus: - Der Ladeanschluss ist leider kein USB-C. Ein Schönheitsfehler. Fazit: Würde ich immer wieder kaufen.

Gutes Gerät - aber die Anleitung ist schrott
Das Gerät ansich ist gut und erfüllt alles, was es verspricht. Nur: Man muss erst herausfinden, wie diess zu verwenden ist, denn die Anleitung ist eher verwirrend. Durch Try and Error haben wir es dann doch geschafft, alle Funktionen zu testen. Technisch ansich 5 Sterne, aber für die mieserable Anleitung muss ich einen Stern abziehen
