This is a brilliant idea!
Was working on a scope at the range and didn’t want to lose the set screws in the dirt. This patch holds really well! Great idea!
I tried to pair the magnetic patch with the all-in-one driver kit, and found out that the driver kit does NOT come with velcro on the outside for the magnetic patch. It would be nice if the company would show pictures of both sides of the outside of the kit, instead of polluting the web with "testimonials" that intrude into my screen when I'm trying to select items to buy - very annoying.
Great way to police your hardware working in the field. Must have for the Fix-it pouch. Going to order another for my range bag.
