Nice quality!

Really good. App is easy to use and seems pretty accurate. We’ve tested it with several people and kept track of what each of us have drank and it matches the amount of units very closely. Obviously I wouldn’t recommend using anything if the law depends on you being sober but this is very good for everything else.

Ça va faire plusieurs année que je l’ai et toujours aussi performant j’ai tout sur l’application j’ai du changer la pile 1 fois depuis que je l’ai !

Solo espera 20 minutos después de un alimento, bebida o cigarro para que el aparato de una medición precisa, no lo he usado con el celular ya que no es necesario a no ser que quieras tener un seguimiento de tu actividad alcohólica :3

Compact and useful for my teenager who has just come of drinking age. A great tool to keep him safe and help him make the right decision when driving (ie not to when he's over).

I don't know how accurate this thing is compared to the ones police use, but it's definitely a big hit at the party! Highest score or just see who processes alcohol better, who's the DD? Whatever the use, it's small and for me fun.
