Useless plastic underwater disposable camera

I paid 1 euro for two identical plastic underwater disposable cameras. Their film was used, I developped both rolls but there was nothing intresting in. The cameras got permanently damaged because taking out the film needed breaking of the camera.
There is only one shutter-aperture combination that I think it is inadequate for a proper exposure underwater.
As there exist many other plastic cameras that can be reused, I suggest to stay clear off this one.
