I wasn’t sold on magnets even when I implanted mine. I just thought it was cool and gimmicky and figured 6m down the road I’ll remove it.
I can’t even begin to tell you how useful it is with small screws and parts.
The best selling point I have right now is when I was changing out the batteries in a small kids toy, on carpet with less than ideal lighting and I lost the battery door screw. A simple pass with my hand found it instantly.
The three minutes it would have taken to find without a magnet doesn’t seem like a lot. But with a screaming toddler demon that’s about 7 hours in destroyed braincell time. Magnet implants are increasing my life expectancy.
