most:
* Information of indoor and outdoor temperatures,
* Signal "gel" and risk of ice sufficiently sound to be audible with a noisy engine,
* Time if needed
and information about the battery condition.
* Easy to install
* Easy setting
no less ...
I recommend this product for people like me who want to monitor their car battery on a "rock" and have information on the risks of ice while driving.
This product is not necessarily a design monster, but performs its tasks without worry.
It is set for myself in a tiny 4/4 tarpaulin and its low price is quite "more than adequate".
