Unfortunately, the cassette turning system seems to leave a lot of gaps for movement, or the head is not of good quality, I don't know, but I have had it since spring 2023 until today, and no matter how many times I have used it, the same issues persist.
It cannot perform the job I want (digitization) well due to instability in the sound. It may not be tragic for someone who wants to nostalgically listen to an old cassette, but compared to a larger, more stable cassette player, this is garbage. And overall, it is very unstable in terms of construction.
