Being an expat in a Middle Eastern country where HIV is taboo and a positive status will surely land you an immediate deportation (unless you're a local which they won't do anything hence the high, but covered up HIV rate) this test could be the difference between being able to pack your bags and leave the country at your own terms or sitting in jail for 3 days and get deported losing all your belongings.
I do agree with the previous posts with using this kit as a "oh I know I'm safe" and some people would turn to bareback as the norm… But as long as the participants are aware of the actual risks involved there's probably no harm in this...
