Despite differences in the principles by which they operate between the participation (Islamic) and conventional banks, there is no huge difference between the products and the services provided by these banks. The distinctive features of the participation banks, compliance with the Islamic precepts, are not the only way for these banks to appeal to the customers. For this reason, customer satisfaction is an important element in the banking sector. The major goal of this study is to analyze the level of awareness and satisfaction among the customers of the participation banks. This study which uses the data compiled through the surveys held in Eskişehir with the participation of 500 Islamic bank customers reveals findings that suggest that most of the customers are satisfied with the products and services by the participation banks and that they have high level of awareness on the Islamic banking products.
