MegaGear Diving Underwater Housing Case O-ring & Silicone Grease Kit for CANON Powershot S80, SD710, SD720, S90, S95, S200, S230, SD400, SD430, ELPH520, WP-DC1, WP-DC6, WP-DC16, WP-DC35, WP-DC38, WP-DC600, WP-DC800

I purchased this o-ring as a backup for the stock o-ring that came with my Canon WP-DC35 (housing for Canon s-90). This o-ring is noticeably larger in diameter than the stock Canon o-ring. Though it keeps water out of the case, because it is larger, the function dial didn't make solid contact with the function wheel on the camera, so i couldn't cycle between different shooting modes. I replaced it with the stock Canon o-ring and didn't have the same problem. I would not buy this o-ring again

It's not the same sizes. I hope it works. I am going to try without the camera on it. It's to big.

Finally went on a diving trip. This is thicker than the previous o-ring and it has a tendency to bulge out of the housing when you close it. However, if I moved it around a little bit it would close correctly. You have to watch the housing closely when closing the housing to make sure it stayed in the channel.

Pedido para una WP-Dc38 de la cámara Canon S95. El paquete enviado pone que es para esa carcasa, pero la goma tiene un grosor muy superior a la original, por lo que la carcasa no consigue cerrar.Intenté forzar la tapa para intentar cerrar, pero se forzaba tanto el sistema de cierre de seguridad que amenazaba con partirse.Por tanto este producto es incompatible con la carcasa.
