I can not understand the negative reviews. Have to admit, however, that I have taken special effort in adapting the SIM card due to the negative reviews. Also, I was especially careful when inserting the card and have all control lines on several occasions that the card survives. It is true that the film has an appropriate thickness. Thus, if the SIM card should survive something then I did not, however, seen with my glasses. For safety, I have something dünnisiert the SIM card on the back with the nail file my wife. Otherwise, the adapters work great with me. I am very pleased that the rise of nano-Sim to Micro Sim went so well.
