The device must be small and match the look of a key or key fob.
The sensor inside must give a clear alcohol level.
A one-button test and a fold-out mouthpiece let you test fast.
The tool must work long on battery power and be simple to maintain.
Some devices can join with smartphones. This is a bonus.
