I just received this article that I have not asked, so I can not give an opinion on its quality, rating sue product appearance. But I would point out two things. First details of the product provided by Amazon does not really help to choose from! The dimensions are those of the packaging !!! Hence the question that can be seeing in the description length and different width while the product is round ... In addition, adhesives on the faces, as ceiling detector are smaller than their unsupported, so there is a portion of non-adhesive coated substrates. These fasteners making 7cm in diameter, the adhesive should make as 6cm. For a detector as the Kidde whose support is 9,5cm of diameter but has a hole in the middle of diameter 5cm, it is not much adhesive bonded to the ring of the detector medium. Nothing to do with the photo, and the 4 (so x2 8 sides) is the same. I am very confused about keeping the product on the detector. So sticking out centering the adhesive on the detector (not the magnetic support itself) and wait to see if it stands on the distance ... Notice after experimentation.
