great product, works really well.
great product, works really well. I used for a service class and passed on the link where to buy it to my service class so it can be used to find damage to an magnetic encoder strip we use on our products.

works at a basic level
This works at a basic level, and what I mean by that is, it will show magnetic fields, but not very clearly. If you have trouble reading them, or looking for more defined readings in general, I would look at another viewer.

Handy to see what items are magnatized
It was interesting seeing different magnetic items with this. It's not very effective with weak magnets though, as would be expected. This is just for those who are as curious as I am and just like to see how things work! :)

Cool! I wish this was bigger size sheet.
I only wish it was a larger cut. Very cool. Buying this piece caused me to buy a larger size. Shop around as once you play with this stuff you will want a bigger sheet for showing off the flux lines!!! I love it and need it all over my walls, floor, and ceilings to show off my magnetic personality hahahahahahahahahahahahahahahah! Thanks for laughing.

It shows clearly things that are thus more easily understood.
Not totally easy to interpret, possibly due to the small size, but at this price it is good and helpful. The small size is handy to use in small spaces, but a small girl is very disappointed that it can't decode EFTPOS cards. ;-) I'm glad I bought it, and use it more often than I thought I would.

Good for price.
Does work, barely as EMF shown in black,. not light as others I have. But for less than $5 is ok.

Barely visible change.
All you see is an indistinct, low contrast slight darkening near the magnets poles. Barely noticeable. A real disappointment.
