Has Tata Play Fire Stick really been successful as a product...i think as they r offering it for free to Tata Play customers without need to subscribe to Binge Plan rather providing 1 month Free complimentary subscription of basic OTT Binge Plan (Don't know if same offer still is available) so some customers might have opted for it but generally it has not been able to make any mark.
Even such Smart Sticks provided by Airtel Digital TV, Dish TV d2h have not been able to become quite popular among people rather it may have just few thousand people opting for it.
Big reason is that people would rather prefer buying Amazon Fire Stick rather than these customised smart sticks bcoz of advantages offered by the former. For those wanting to watch Linear TV Channels + OTT services android / smart boxes is the best option. One needs to have active DTH Account status to access OTT on both Android box and Smart Sticks...also there is probability of operators bringing in some more terms & condition like mandatory subscription to basic OTT pack for Smart Stick users hence it is best to not opt for it...if it gwts damaged while using then Tata Play will charge the customer full amount for it which will be lot more than a New Binge Box
