15pcs Slip-On Wrist Compass Hard Shell Liquid Filled Mini Small Button Compass Paracord Bracelet for Outdoor Hiking Survival Wrist Watch Band 3/4" (20mm)

Good deal.

I saw one review video where the guy called these things garbage... while wearing a giant smart watch right next to the compass. For those new to compasses, electromagnetic fields will cause spurious readings. Compasses cannot tell the difference between magnetic fields caused by the Earth and those caused by electronic devices. Electromagnetics 101: electrons moving through wires generate a magnetic field. More electrons moving around means stronger magnetic field.These seem to work perfectly fine on my basic digital watch. Walking on a treadmill seemed to generate enough of a magnetic field to mess with the operation. Keep these away from electronics, magnets, and particle accelerators, and they should work fine. The quality of the mount is not the best, but 5 stars given the price point.

Thought they would be working compasses but I found they don't. Cute for craft idea tho.

I like them, they seem to point north no problem and they fit on just about every watch I have.

These things are definitely just a novelty item. They are 100% not accurate tested in several areas on hard table on a flat surface walking around and holding them etc. every time it told me a different direction was north at some point don’t waste your money they do not work.

Made some bracelets with them and they work good for that and work well.

Muy bueno!!
