A cumbersome and lengthy complaint from the manufacturer (with photos of the different measurement results) brought, as a result, that the device is fully functional!
And not unimportant: the measuring head, there is a recess in which is deposited the perfectly normal earwax. Because there is no sterile measuring cap. That is the next point ko-hygienic point of view.
Actually, by now unimportant: the announcement voice is annoying because you can not interrupt if you still want to make a measurement to control quickly. (Sure, we could also somehow off, but it would be helpful if the measurements ...)
Breuer I am used to better.
