I was also afraid of testing the site because I didn't know how it works, though when I clicked it gives me exactly what you share here but wasn't that cool with it, I think the best is for them to launch a review campaign where people would have to test their services and give feedback to it and of course for them to gain attention and exposure here running a review campaign would be the ideal thing to do.
They have been running for almost a year, I dont think they need to launch review campaign because the service itself is simple to use especially for those who are familiar with Stake and its tipping feature.
They have gained such a decent volume since their launch, they had signature campaign as well in the past and I think they do not need any campaign again now.
If you want to try, you dont need to worry or afraid, because the minimum amount to exchange is less than a dollar, if you have $1 in your stake's account, you can try it unless you are afraid to lose $1.
