I have been a customer of Sistemas informaticos abiertos s.a for a few years now. Overall, I am satisfied with their services. The website seisen.es is easy to navigate and the products they offer are of good quality. The staff is helpful and professional. However, there have been a few instances where I experienced delays in receiving support. Despite that, I would still recommend Sistemas informaticos abiertos s.a.
