With the installation and commissioning of the CRYRING@ESR facility being largely complete, the first heavy ion storage ring of the FAIR facility in Darmstadt is now in service as a user facility. The ring is able to store all ion species the GSI accelerator complex can produce as beams -- from the lightest protons to bare uranium -- and operates at significantly lower beam energy range down to few 100~keV/u. This opens new experiment opportunities and the SPARC collaboration at FAIR has proposed a rich research program on precision spectroscopy, slow atomic collisions and astrophysically relevant processes. During the 2021 beamtime period, first experimental installations of SPARC were successfully taken into operation and several experiment proposals were taken to data production. Even though the data analysis is still largely ongoing, it has already become apparent that the performance of the facility is largely meeting the high expectations. In addition we have been able to identify realistic opportunities for further improvement. We will give an overview of the storage ring, its performance, available and planned experimental installations, and invite discussion on further opportunities of the facility.
