Seems accurate. The beeping sound is annoying as you blow, but it is there to let you know how long to blow.

Not reliable

These are not reliable at all if you plan to test yourself before driving. I have tested myself after a few beers and the test varied too much within minutes.

Since there is really no way of knowing how accurate this is, it is hard to comment on it, however it does "seem" to work well as advertised.
