Is a complete scam , they ask you when booking to share the link to 5 friends and you cannot get even on the waiting list if the 5 friends are completing their also journey to another 5 friends and so on. A complete scam to get your personal data and to share their product to more people , is just market strategy on their customers patience. A star is a lot , I would give 0 stars as I know is just a data colection process. They called themself a medical device testing provider it's a shame for industry !
