Straightforward, light use test tool.
Simple easy to use circuit/voltage tester, probably not sturdy enough for daily use but compact to use as handy occasional tool.

Clip too weak for spring, prong broke off-day 1
within an hour, had to superglue the copper prong into the recess- it broke off almost immediately. The coiled wire is too strong for the clip ( clip too weak). Poorly made

Good value
Arrived and done the job nicely ideal for a cheap fuse tester

Great tool
Simple & easy to use, a little worried about the longevity of the switch as it feels a little flimsy but working well so far.

Hammer Teil
Hätte nicht erwartet das das Multimeter so genau ist. Des Weiteren gibt es drei schalt Stellungen, gerät aus, dioden prüf Lampe und Multimeter und das so krass kompakt das Kabel lässt sich ein wenig mehr als einen Meter ziehen, mehr würde ich nicht empfehlen. Die Krokoklemme beißt auch gut zu die Verarbeitung passt für das Geld und das Kabel macht auch einen soliden Eindruck. Alles in einem ein super Gerät um stichprobenweiße Spannungen zu prüfen oder Signale sichtbar zu machen 👍🏻 .
