This is a review of the GoPro Suction Cup Mount AUCMT-302. I found it to be very durable and easy to use. I highly recommend this suction cup as a way to effectively mount your GoPro action camera to any flush surface.
I have a lunch box locker and it ratchets when turning, basically locking and unlocking to make the turn. do a search on how lunch box lockers work and you will find lots of videos that explain it better than me.
