Are these the ones that you will have to pay a fee on? If so if I buy a new stick will I still have those charges
There are NO Roku models that you have to pay a fee on, no matter how old they are. There are no charges just to use a Roku. Anyone charging you to register and/or use a Roku is a scammer thief trying to separate you from your money.
There are specific channels, however, that may require you to purchase a subscription in order to watch.
