Displays lots of different weather data. Lithium battery lasts several years (with occasional use).
* If you close the jackknife all the way--or even most of the way--you can't pull it open again. but you need to close the jackknife to change the battery (it seems) Several friends also tried without success to open my device.
* It only displays one datum at a time. If you want to continually look at wind speed and temperature for example, you have to cycle through all the other data items to go from one to the other. Huge nuisance.
