Hello. I bought the Floaty Backdoor for Gopro, since I am an avid water sports enthusiasts and in the near future again go on the water. Since I am now the happy owner of a Gopro, I bought this to secure the Floaty. I bought the original for several reasons. Although you get a similar floating body, which probably also fulfills its purpose, but stop just not an original for a fraction of the money. Furthermore, I am convinced that there is no one like a to go Knallorangem float ski or snowboard or even parachuting. For that is an advantage or disadvantage of Floatys because it is firmly glued to the Backdoor GoPro. Advantage: Very safe and by the 3M adhesive pad you get this barely down, Small disadvantage: It no longer gets down. The advantage of this product is namely that one bekoerenmmt in set two backdoors, once for 3+ and 4 and again for älten models. This has the advantage that one has firstly a backdoor to top gluing and compared to the other offerings is also original. Who wants to destroy his Gopro only because 5e? The door closes cleanly and leaves no drop of water pure. Excellent. The nice thing about this design is that the 3M adhesive pad is very large and therefore almost all the backdoor cover. Large surface => Large adhesive surface => Better grip. Also important seems to me the color choice of Floatys, so it is also in and on cloudy water visible from afar and you can easily find if you've lost it, for example, when diving. Simply shows up and then floats on the surface. Even the included Thether, so backups are very good and provide enhanced for securing the Gopro, because if once, what one does not hope that bracket breaking, so the Gopro depends on the adhesive chopping and you can safely bring ashore. Since this is external, ie specially glued, it can not happen even if it (hard to imagine) dissolves the glue of the holder, the Gopro to the adhesive chopping keeps securely. I do not happen again, that he fell while skiing and the helmet has noticed a and thereby immobilization has jumped out of the holder. Luckily he had moored a glue hacking addition to the actual holder and can today enjoy his Gopro. From all the above points Stick I can only highly recommend to the Originalfloaty zuzulegen, because in this case should not pay attention to the money but the quality one. Therefore again: save for safety thrift, because 5 and then lose the Gopro not pay off. Your Prometheus. PS: ask questions if something is still unclear. PPS: Longitudinal Study Follows
