Bought for use at work for analyzing magnetic fields and devices. Has super clear picture versus other products.

My kids have really been enjoying carrying this all over the house and finding the magnets hidden in everything. It works like magic! They found magnets and more things than I could’ve imagined.

Bought as a gift for a child and tested it out on a wide variety of strong and weak magnets. Nice size, very sturdy, detailed imagery. No ghosting. I liked it so much I’m going to get one for myself. Price seemed good at the time of purchase at less than fifteen.

This is only 3.5" x 5.5" viewing area, about 20% less than the advertised 4" x 6", and not much larger than the cheaper but better 4" x 4" displays.It works ok, and it's better than the older style, but it's not as sensitive or clear as the popular brand product.The frame prevents getting magnetic impressions from items near edges and corners, and the paper frame doesn't appear easily removable, so using this is damp or greasy environments isn't good.

I find this magnetic field viewing film to be the right size to check most common magnetic object. It does a decent job in revealing the magnetic field around without any after effects, the film instantly resets when the field is no longer present.I don't see any practical benefit from using other than checking for unsuspected magnets or simply exploring the field of each magnet.I don't find it useful to tell a strong field from a weak one, I'm sure it does, but it'll take a trained eye to be able to tell.

Running it over the phone, laptop and fridge magnets looks just like the photos. Much better than the plain green version I bought years ago (which is still very cool, just not as colorful).
