Reviewer HD_Dil (September 6, 2025) noted the 'wide variety of options' while expressing desire for enhanced same-fighter parlay capabilities. Rob88187 (July 29, 2025) praised the platform as their 'top rated' DFS app despite verification delays, while Bigsmitty1981 (July 25, 2025) specifically highlighted the best ball functionality.
