Outil super efficace pour vérifier que les prises électriques sont bien branchées. Les lumières LED sont clairement visibles et les instructions sont clairement inscrites sur l'appareil. C'est parfait!

Works as advertised. Easy to use and read. The colour of the lights could be better, so the printed on instructions are a bit unclear for like a millisecond, until you realize you can just count the lights instead.

Bel achat,

Not as nice as the pen version but works flawlessly

Works well at a great value.

Tested a few outlets and Works well.
