First, I must say that I both completely opposite Reviews (glued or not glued) can understand. I need both adhesive plates, namely for dashboard mounting the VW Tiguan on a slightly textured and curved surfaces as well as the Honda Jazz in smooth plastic. The first impression was that the plates do not stick. They were deducted again with minimal effort and also when touching the adhesive surface with your finger I did not have the impression that this may be something. Nevertheless, I have the adhesive plates initially pressed to the desired locations, and went into the house frustrated. About 2 hours later, I was - with double-sided tape and scissors - reissued to our cars to fix the panels permanently. Much to my surprise both plates glued firmly now and held the first tentative and later becoming massive checks of adhesive strength was. After now more than 2 weeks and several Saugfußwechseln from one to another car to keep the boards still and raise the hope that this will permanently remain so. I still have to deduct a star, because my positive knowledge is based solely on chance. One would have the items at least must enclose a note which informed that unfolds the adhesive effect only after some time.
