This is exactly what I was looking for. I found it an excellent choice for my needs testing circuit boards.
Probably the lowest price for DC 6-24V Copper Voltage Test Pen available in a lovely webstore!
Excellent tool! It arrived yesterday and at 8pm already resolved a problem with my neighbour about his generator.
Just what I was looking for. Paid for itself in 1 days work. All the tools I needed to upgrade my electrical outlets easily and safely.
I bought this to find wires in my wall for a light relocation. It works good, however, I had to ask my friend to help me out with this tool.
Great tester for my RV. Used everything and all works perfectly. Pops is an electrician and said it’s great value. He said he might buy it as a backup tester.
Come to find out using this tester, the outlets in the kitchen were very much live circuits while others in the house were not. If I have not used this product I might not be here today.
