Solenoid Tester, Solenoid Magnet Tool to Detects Ac Fields, and Rotation Tester for Circulating Pumps

Doesn’t work at all. Doesn’t spin on an energized coil. Does not detect motor rotation either.Update, it fell apart within 1 week

The media could not be loaded. Great product. But only works for majority of circulator. Quick circulator check.

The item works just fine. However it's pretty brittle and doesn't do well on a key chain. I crushed mine the first week I had it crawling on top of a walkin freezer.

I use these at my job and I will have to spend more money as this one does not work! It was embarrassing when others had ones that worked. Maybe it was a bad one but I would like a refund. Normally good products at Amazon but this one not worth the money or hassle

I've had these in the past from other manufacturers, and this is the first one I've ever had just simply not work. It just wont spin when placed over an energized coil.

Why nice idea

The media could not be loaded. See video

It only works with a few selected type of circulator pumps.Not good quality.

works ok but a little bit cheap buy a better one
