10/26/21. Batteries went dead again. I will continue to post when they go dead. It is unbelievable and just VERY POOR CUSTOMER SERVICE that you have not responded to me on this issue. **BUYER BEWARE**. Roku is selling a bad product and will not help you when you reach out to them. There are several other products that do the same as Roku and have better customer service***DO NOT BUY**. Get a fire stick you will be much happier
