The item is as described. The function is given and the material is good. The assembly (the bicycle) was simple and self-explanatory. I own an S3 with Otter Case and Samrtphone still just fits into the holder. The gums are, however, at the limit. More is not possible. The maintenance is however given and the function is not restricted. What the two small stickers are schwaruen, has me but not identical tapped. This probably come into the side brackets to protect the sides of your smartphone.
