ValtcanWrist Strap Grounding Tester Anti-Static ESD Test Ground Wires Test Device Only

Works as described, was able to check grounding of grounding sheet, I bought on Amazon, my it was well grounded. Able to check other areas like trees, ground, and deck. I also got The Earth Prescription by Dr Laura Coniver, that’s explained how to use it.

Didn’t work

This product works exactly as described and expected. The buzzer is plenty loud and the lights are clear. Very simple to use and definitely works to show both low and high impedance strap connections.

This is really an amazing piece of equipment. I have been improving the ESD capabilities of my lab including ground mats and this works great to tell when I have continuity and when I don't. As a professional engineer, I wonder how I lived so long without it. Highly recommended.As a side note - it gets 4 stars because it came without a battery and the battery clip doesn't stay on the battery. I made due because it was just the 9v battery clip, but attention to detail would have easily earned this 6 stars.

Good product, simple and easy to use. Only problem was that device didnt come with a battery and warranty seal needs to be tampered with just to get into device to put a battery in. Description states its suppose to come with battery

Very simple to use. Just install 9V battery and start using. It is accurate and has very simple to read indicator lights to figure out if your wrist strap is working properly.

Not what I expected. I do grounding and wanted to check if items were grounded. Didn’t work for me.

It was easy to use and test my old strap
