Actually I'm considering buying such a thing.
I hardly ever drink, but this is starting to be nit-pinking.
Over the limit is far from being drunk as far as I know, so there is no way to assess if you are just over or under the limit.
And yes; not drinking is THE solution, but sometimes it simply happens you have 1/2 a glass too much!
Its a matter of "covering your *ss" like with every small aspect of our job!!
Not that I think we're above the law, but It got pretty easy these days to loose your job as a pilot these days!
If it would be as easy to get job as to loose it, everyone would be a pilot!
