Great! I'm sure Andrew and Jason got theirs as well considering you're all in MN.
After a week of driving (Monday I had hit 90mph+ in traffic...long story), all of the magnets are exactly where I put them. EVEN the teeny tiny ones I bought earlier which are more than 5 times weaker than the 1" magnets. I was skeptical that the small ones would stay put, but all 5 of them are still there.
That tells me the 1" ones we all have now are not going anywhere - unless you happen to drive over a super-large neodymium magnet in the road.
