I buy this camera to get a better sound capture through a tie microphone, this case is convenient because you do not need to leave the camera to connect the cables or exit the SD card. I used onboard a kart cross without connecting a microphone in addition and the sound is much better than with the waterproof case and the perforated lid. The only small problem is that the cover seal takes much dust and request to be cleaned. But it's the same on the waterproof case.
The only flaw is the price, it would have been five stars to go.
