KeyBarKeyBar Medium Magnut, 1.5" Overall, ACS-AL-MN-MD

Glad I got the medium as I think the small would be too light duty. Looks great and functions flawlessly.

not afraid of losing my keys

Does what its supposed to do---quick separation of keys when needed.Yet when connected you can be confident in the strength of these magnets to securely hold everything together and keep them that way in your pocket or out.Glad I got the medium size version. Not perfect---yes, the magnets can entangle themselves with nearly anything metallic (save non-ferrous metals like brass, aluminum or titanium) but that aside, its a good, useful product.

Magnet is very strong !(received the medium size as a Xmas gift)It was causing the immobilizer in my car to go off (anti theft) which turns off fuel pump/ignition etc. when trying to start. took me days to figure out why. Removed the magnet from my keys and voila... No more issues .
