Here's what 3 happy customers said about us on our Google Page:
It was ordered to test the theory that Covid-19 vaccines had made some people to be magnetized. The two I have checked have not proved to be so. The little magnets work very well. The only thing I would suggest is to be more explicit in warning about staying away from TV, computer, etc. with respect to actual distances recommended.

The danger to electronics is meant to be a general one. A tiny magnet up close will have no effect. A big one right up against a hard drive or monitor can cause some grief.
