FIELD TESTING, SORT OF
What's actually on my keyring
This is why KeyRingThings exists. A keyring can be a tiny toolbox, flashlight drawer, emergency kit and gadget collection that happens to start your car.
“And it's currently missing several things that are usually on it.”
The eventual version of this page can identify each item, say whether it earns its weight, and link to the exact product or the best current replacement.
