What was negative:
The reason why I do not give 5 stars is the following.
When trying the display with the narrow "plastic siphon" to raise, this is immediately broken.
Whether this was corrupted from the beginning I have not checked, this I suspect, however, because I can do no great power to him.
(Change the battery) for my purpose has this set perfectly fulfills its purpose and is classified in the optimal price at around 5.
