The magnetic wristband is one of those tools that sounds like a novelty until you've used one on a job where you're constantly picking up small fasteners, screws, or wire nuts off a floor or out of a box while your hands are full of something else.
What It Actually Does for You
Keeps screws and fasteners on your wrist instead of in your mouth or on the floor. Eliminates the repeated set-down-and-pick-up motion when you're working with both hands. On jobs involving a lot of device installation — outlets, switches, cover plates — the time savings over a full day are real, not marginal.
KUSONKEY Wristband
20 neodymium magnets. Holds a meaningful amount of hardware, not just a couple of screws. Adjustable strap. This is the one I reach for on device-heavy work. Strong enough to actually hold things, comfortable enough that you forget it's there.
KUSONKEY Magnetic Wristband — 20 neodymium magnets. Strong hold, comfortable fit.

Nine neodymium magnets with wrist support and a thumb loop. Different ergonomic design — the thumb loop keeps it positioned correctly during repetitive wrist movement. If you're doing overhead work or ladder work where the wrist position changes constantly, the thumb loop design stays put better.
BINYATOOLS Magnetic Wristband — thumb loop design, wrist support, 9 neodymium magnets.

Hold plastic anchors, non-ferrous hardware, or anything that isn't ferromagnetic. Doesn't work with brass or aluminum fasteners. This is obvious but worth saying — check what you're working with before you rely on it to hold something.
