So my predecessors have the device so badly badly rated. I use the Cam for underwater shots and had even with 20m. She was close. The included key ring for attaching certainly is not the best alternative, but the one can agree. The attachment's bike for I have not tested, so I can not judge. I had the cam using the supplied rubber band on your wrist mounted but better yet, take it at the movies right in your hand and holding on to the movie object. With the image quality I am quite satisfied, so for me it is enough. Am not a professional photographer! OK you have to connect the cam to the TV to make adjustments, not going to the PC, but I can live with. Unfortunately, the need to Micro SD card sold separately. One should already use an 8GB and Class6 Card, is also recommended so. So for the price I am fully satisfied, as I said, I have done only underwater shots. Sound quality is also ok. I have expected for the price otherwise and can not complain. Better a simple UW Cam, as an expensive which might sink me under water, because the seals are so sensitive to the housing.
