I just received the case. I thought I would use it on the camera on the mirror. However, it is not possible. The dimensions they mention for the medium and definitely for the L XL are wrong.... So, for the M size that I got, they mention dimensions M: 150 x 85 x 30 mm but those are external dimensions that we are not interested in. Internally, the dimensions are two centimeters smaller.... I thought I would put it on the mirror but it is made to fit on a thick tube like a bicycle handlebar.
So, I do not recommend buying it. Avoid it so you don't lose even those few euros it costs. To the stores that sell it, I would kindly ask them to reconsider the size specifications because the ones listed are not correct. We won't be able to stick the phone on it. We will put it inside and the given sizes are not accurate.
