I have a Polaroid Cube+ on a chest strap. I needed a way to level the camera (make it horizontal so it's pointing straight) without using Wi-Fi. The camera is housed in a waterproof case. I use two bubbles, one on each side of the case. A bubble confirms another bubble. These bubbles are the perfect size to fit on your case and work great! I used thin double sided tape. All 10 bubbles worked correctly the first time! I recommend these bubbles.
