Update 2. Delivery:
The animals do now, what I bought it ;-)
But there's 4 stars.
A lack of the very purpose "dog toys".
There is not likely to have the cheap plastic cast from China ago.
Since each cloth or a cloth cord is much more suitable, if only by the durability.
Update 3. Delivery:
2 more ordered and both of the defective acoustics again!
Obviously, there are two versions: one with red mouth without CE mark: squeaks
Without red mouth with CE marking: No squeaks
For most, however, does not seem to be completely irrelevant for my purpose. In so far as only 3 stars remain.
