Independent shopping perspective
The Korena take
A plug-in tester for 110V outlets. Shows wiring faults and trips GFCI outlets so you can check stage or studio power before setting up gear.
Strong match
Who this is for
- Checking venue outlets before plugging in an amp rig
- Verifying studio power is grounded and wired correctly
- Testing GFCI receptacles trip properly in a rehearsal space
Consider the trade-offs
When to look elsewhere
- Anyone needing 220V or international outlet testing
- Detailed electrical diagnosis — this indicates faults, not causes
- Use as an audio device; it does nothing to signal

Detail 03
Indicator light pattern
Light combinations point to open ground, reversed polarity, or open neutral — the faults that cause hum and shock risk.
Detail 04
Plug-in operation
No batteries or meter leads. Insert it in the outlet and read the lights.
Final check

- 02Tripping a GFCI cuts power to everything on that circuit
- 03It flags a fault; correcting it is an electrician's job
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this tell me if an outlet has a bad ground?
Yes. An open ground is one of the wiring conditions the indicator lights identify, along with reversed polarity and open neutral.
02Does it work on non-GFCI outlets?
It still reads the wiring condition of any standard 110V three-prong outlet. The GFCI trip test only does something on a GFCI-protected receptacle.
03Can this fix ground hum in my rig?
It can identify an ungrounded or miswired outlet as the source. Fixing the wiring is separate work.
04Do I need batteries?
No. It draws what it needs from the outlet you are testing.
