Chaos at the Shenzhen market, scams, viruses, refunds, bait-n-switch, and dodgy meters - the infamous $9 AIMOmeter AMPX1 0.02% Process Calibrator delivers!

Test footage from the first run Kickstarter developer prototype 360cam 360 degree waterproof HD camera from Giroptic
As you can see, the quality isn't that great, and the audio is terrible, this came directly out of the camera. Not sure if it's a PEBKAC or a genuine issue. But it is a first run developer prototype.
NOTE: There are some reports the 360 feature only works on Google Chrome
