Not efficient - Rothco Carabiner Compass/Thermometer

The magnetic force on the compass is so weak you have to shake it to free up the wheel so it's slowly Points North. And it must lay perfectly flat. 1 degree off and there is too much friction in the compass wheel to turn. Thermometer is very small to where it takes a few seconds to focus on the small numbers. The thermometer glass is sunken in a groove to where you must have light shining on it to see it. The aluminum Carabiner hinges at the top so it doesn't clip on objects very well without having to move it around to get everything to fit. This product had three jobs, and it fails at all three.
