Yes we bought a Randox test as a test run. Had to input your details to the app 1st - passport number + photo. Once your profile is set up its all straight forward. I actually done the test before setting up the profile on the app. Literally a few clicks, then had to wait 15 mins before could take a pic of the test. Then just a case waiting for your email - which in my case was 5 mins. The hardest part was taking a photo of the passport- it was saying show the front, then saying too close, then show the back, was about to try and start again as didn't really know what I was doing and then all of a sudden it accepted the picture. Hopefully now it's all set up will be straight forward when doing it for real
