They are honest, forthright, and communicate with their clients throughout the process! I would absolutely work with them again, if so possible.

This website has the lowest ranking of trust and also very low number of visitors. Consult any scam advisor online. The site, the company and their quoted ‘kind interviewing employees’ mimic online survey companies. Be aware of some ‘client’ reviews (Trustpilot) that claim to be a genuine experience, either through naively attitude or social engineering. Predatory behavior in mailing with suspicious intentions.** Do not exchange ** any personal or business details to them, as this may enrich their next attempt to support and flatter your ego. This then could lead to (personal or business) identity fraud.

My experience at SIS was fantastic. From the quick check in to getting paid same day in cash, this was a straightforward process. The group was interesting and I was in a room with a bunch of lively characters, making the time pass so quickly. I felt that I was paid more than fairly for only being there for 90 min. Overall, I would highly recommend.

SIS is a great research company. I was a participant, and I had a wonderful experience. The whole process was smooth from the start to finish. The staff was very professional and welcoming. Thank you.

SIS was great to work with--the building and the conference rooms were easy to navigate and very clean. Facilitators and administrators communicated directions clearly, the food we got to try was tasty, everything operated on a timely manner, and we were paid in cash day-of.
