For 2 euros, it's okay, but you can't trust it to hang for a long time without adjusting its position, and it definitely won't hold the phone in more intense movement (running, dancing). The plastic card that goes inside the case is made of very flexible and thin plastic, which after a few pulls starts to slip and gradually come out of the case, causing your phone to fall if you're not careful. I will try to stick it with double-sided tape to make it more stable. It's okay for simple use, but if you want something more stable, look for a higher quality solution. The cord is very good, adjustable, and doesn't bother. Although it says it's for the neck, it's long enough to cover a diagonal passage.

Update: The plastic broke after 4-5 months of use.

It looks very sturdy. If the fabric that you put inside the case to hang the cord was transparent, it would possibly be better because it doesn't look very nice in a transparent case.
