A:Answer There are 3 primary options available. The Roku Streaming Stick, Roku SS Plus, and Roku Ultra, with Ultra being the "best".
The basic Roku Stick offers 1080 HD picture and has a smaller receiving range. While it still may receive a signal anywhere you place it in your home, it may be limited or spotty if say, you're placing it far away from your internet source. The other downside, (from what I'm told,) is the remote needs a more direct "line of sight" to register your inputs.
Roku SS Plus features 4K picture with HDR. If you own a 4K TV, this is truly your option. Even if you don't and still use a 2K (1080) TV, this WILL still work, and will auto-detect your TV settings during setup. Also, its receiver is powered, so it will pick up your internet signal much better.
Roku SS Ultra has all the features of the Plus, but includes an SD card slot and an ethernet port so you can connect directly to your internet, rather than via wifi.
We recently began cutting cable, purchasing a TCL Roku TV, as well as a Roku SS Plus for my mother's apartment in our home. We spent a bunch of time ensuring that (with the purchase of the Roku TV included,) the money was well-spent. The TV is an EXCELLENT value, and when it comes to the Roku SS Plus, it was also an excellent purchase. My mother's TV is a 1080, and during setup, the stick detected it and offered settings to choose from, so compatibility is excellent. We've had this for a few weeks now, and there's been no issues. If you own or plan on owning a 4K TV, or if you have areas in your home where the wifi signal is not consistent, the Roku SS Plus is an excellent choice.
