Several years of experience using TANGO Control system are discussed in this paper. Construction of Linear Induction Accelerator (LIA-20) was the driving force for introduction of TANGO in Budker Institute. In the frame of this project, significant number of TANGO Classes for different types of hardware were developed and basic program infrastructure was provided. This progress made it feasible to apply TANGO to other facilities. Therefore, it was used in some subsystems at VEPP-2000 and vacuum stand. This paper presents overview of construction of TANGO based control system. The problems, which arise during its introduction to existing control system, are discussed as well.
