An adult may not appreciate it, but because it is for children who enjoy other things, I will say that yes, it is okay. They have had it since last year and played with it for about 8 months - during the quarantine, let's not forget. The microphone is fine, the little bag is fine too.

There is nothing special to justify spending 28 and 30€.
Only with the microphone can you say that the child will be engaged, but you can get something much better for the same amount of money!
