    We have been working with iFlair for over 5 years now. At the beginning the process of “recharging credit” was a bit strange for us. But right after the first day of development we got a very good job. In the meantime, we have implemented over 5 major projects with over 10,000 euros with iFlair. Never with problems. We can only highly recommend the work and look forward to continuing good cooperation.
